При инсталляции системы Gentoo Linux x86_64 возникла проблема с пакетом kde-base/kde-meta. Установку пока провожу из под chroot, используя Live-CD System Rescue CD. В данной системе пробую, по возможности, максимально отказаться от использования программ с тестовой ветки "~amd64"
Приведу текст похожего вывода сообщений, который был у меня, однако свой я не успел опубликовать, потому взял отсюда link

Ставим мета-пакет:

emerge -p -av kde-meta

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/qt-gui-4.6.0:4[accessibility,dbus]".
!!! One of the following packages is required to complete your request:
- x11-libs/qt-gui-4.6.2 (Change USE: +dbus)
(dependency required by "kde-base/kdialog-4.4.4" [ebuild])
(dependency required by "kde-base/kdebase-meta-4.4.4" [ebuild])
(dependency required by "kde-base/kde-meta-4.4.4" [ebuild])
(dependency required by "kde-meta" [argument]) 

Добавляем требуемый флаг в /etc/portage/package.use/x11-libs

x11-libs/qt-gui dbus 

Опять пробуем установить мета-пакет:

emerge -p -av kde-meta

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/qt-sql-4.6.0:4[qt3support]".
!!! One of the following packages is required to complete your request:
- x11-libs/qt-sql-4.6.2 (Change USE: +qt3support)
(dependency required by "kde-base/kdialog-4.4.4" [ebuild])
(dependency required by "kde-base/kdebase-meta-4.4.4" [ebuild])
(dependency required by "kde-base/kde-meta-4.4.4" [ebuild])
(dependency required by "kde-meta" [argument]) 

Опять добавляем требуемый флаг в /etc/portage/package.use/x11-libs

x11-libs/qt-sql qt3support 

Снова запускаем команду:

emerge -p -av kde-meta

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/qt-core-4.6.0:4[qt3support,ssl]".
!!! One of the following packages is required to complete your request:
- x11-libs/qt-core-4.6.2-r1 (Change USE: +qt3support)
(dependency required by "kde-base/kdialog-4.4.4" [ebuild])
(dependency required by "kde-base/kdebase-meta-4.4.4" [ebuild])
(dependency required by "kde-base/kde-meta-4.4.4" [ebuild])
(dependency required by "kde-meta" [argument])

И вновь добавляем требуемый флаг в /etc/portage/package.use/x11-libs

x11-libs/qt-core qt3support 

Пробуем снова установить мета-пакет:

emerge -p -av kde-meta   

These are the packages that would be merged, in order:

Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

x11-libs/qt-core:4

  ('installed', '/', 'x11-libs/qt-core-4.6.2-r1', 'nomerge') pulled in by
    ~x11-libs/qt-core-4.6.2[-debug,-qt3support,-aqua] required by ('ebuild', '/', 'x11-libs/qt-opengl-4.6.2', 'merge')

  ('ebuild', '/', 'x11-libs/qt-core-4.6.2-r1', 'merge') pulled in by

    (and 36 more)

x11-libs/qt-gui:4

  ('installed', '/', 'x11-libs/qt-gui-4.6.2', 'nomerge') pulled in by
    ~x11-libs/qt-gui-4.6.2[-debug,-qt3support,-aqua] required by ('ebuild', '/' 'x11-libs/qt-opengl-4.6.2', 'merge')

    >=x11-libs/qt-gui-4.6.0:4[accessibility,dbus] required by ('ebuild', '/', 'de-base/solid-4.4.4', 'merge')
    >=x11-libs/qt-gui-4.6.0:4[accessibility,dbus] required by ('ebuild', '/', 'de-base/kmenuedit-4.4.4', 'merge')
    ~x11-libs/qt-gui-4.6.2[qt3support,-aqua] required by ('ebuild', '/', 'x11-lbs/qt-core-4.6.2-r1', 'merge')
    (and 34 more)


It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
installed simultaneously. You may want to try a larger value of the
--backtrack option, such as --backtrack=30, in order to see if that will
solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man page
or refer to the Gentoo Handbook.


emerge: there are no ebuilds built with USE flags to satisfy ">=dev-python/PyQt-4.7[dbus,sql,svg,webkit,X]".
!!! One of the following packages is required to complete your request:
- dev-python/PyQt4-4.7.3 (Change USE: +sql +svg +webkit)
(dependency required by "kde-base/pykde4-4.4.4" [ebuild])
(dependency required by "kde-base/plasma-workspace-4.4.4" [ebuild])
(dependency required by "kde-base/kdebase-meta-4.4.4" [ebuild])
(dependency required by "kde-base/kde-meta-4.4.4" [ebuild])
(dependency required by "kde-meta" [argument]) 

и видим конфликт, что требуется изменить USE-флаг +qt3support на ему противоположный -qt3support у пакета x11-libs/qt-core

Выход оказался простым, необходимо добавить в список еще один пакет x11-libs/qt-opengl с флагом qt3support

cat /mnt/gentoo/etc/portage/package.use/x11-libs | grep /qt-  
x11-libs/qt-core qt3support
x11-libs/qt-sql qt3support mysql
x11-libs/qt-gui dbus qt3support mng
x11-libs/qt-opengl qt3support

После чего началась установка kde-meta (у меня из состава 333 программ, перед этим уже был установле gnome). Одним словом, пока оно компилиться, можно спокойно пойти попить чай.
