KDE-4.2.1 проблема при сборке.[РЕШЕНО]

Доброго времени суток уважаемому сообществу!
Возникла следующая проблема. Пытаюсь поставить КДЕ на работающую систему с установленым XFCE4 обновляюсь, запускаю emerge -p kdebase-startkde и получаю на выходе следующее:
.....
[ebuild N ] kde-base/krunner-4.2.1 USE="opengl -debug -kdeprefix -xcomposite -xscreensaver"
[ebuild N ] kde-base/kdebase-startkde-4.2.1 USE="-kdeprefix"
[blocks B ] media-sound/phonon ("media-sound/phonon" is blocking x11-libs/qt-phonon-4.5.0)
[blocks B ] kde-base/phonon-kde ("kde-base/phonon-kde" is blocking x11-libs/qt-phonon-4.5.0)
[blocks B ] x11-libs/qt-phonon:4 ("x11-libs/qt-phonon:4" is blocking media-sound/phonon-4.3.1)
[blocks B ] x11-libs/qt-phonon ("x11-libs/qt-phonon" is blocking kde-base/kdelibs-4.2.1)
