[gentoo-user] How do I fix multiple versions for the same package slot have been pulled

[John covici <covici@ccs.covici.com>]

In my latest update I have received the following message:
!!! Multiple versions within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

media-libs/win32codecs:0

  ('installed', '/', 'media-libs/win32codecs-20071007-r4', 'nomerge')
  pulled in by
    ('installed', '/', 'media-libs/realcodecs-11.0.1.1056', 'nomerge')
    @world

  ('ebuild', '/', 'media-libs/win32codecs-20071007-r4', 'merge')
  pulled in by
    ('ebuild', '/', 'media-video/vlc-0.9.6', 'merge')
    ('ebuild', '/', 'media-video/mplayer-1.0_rc2_p27725-r1', 'merge')
    @world


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.
 
Are they doing some kind of strange reorg or what?  HOw can I fix
this?

Thanks.
