[LUG.ro Mix] problema de actualizacion en gentoo

[Fabrizio Cutro]

Tengo un problema con gentoo,  quiero realizar una atualizacion completa con 
el comando "emerge --deep --newuse world" y me salta el siguiente error:

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

x11-libs/qt:4

  ('ebuild', '/', 'x11-libs/qt-4.4.2', 'merge') pulled in by
    x11-libs/qt:4 required by world
    >=x11-libs/qt-4.3:4 required by 
('ebuild', '/', 'dev-util/cmake-2.6.2', 'merge')
    >=x11-libs/qt-4.3:4 required by 
('ebuild', '/', 'app-text/poppler-bindings-0.10.2', 'merge')
    (and 2 more)

  ('ebuild', '/', 'x11-libs/qt-4.3.5', 'merge') pulled in by
    =x11-libs/qt-4.3*:4[dbus] required by 
('ebuild', '/', 'app-misc/strigi-0.5.11', 'merge')

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.

Desde ya muchas gracias........
