As Michał already noted in this thread, dynamic deps does not play nice
with slot operators. So I had the same problem with "2 GNOME related
packages":

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

virtual/udev:0

  (virtual/udev-208-r2::gentoo, installed) pulled in by
    >=virtual/udev-171:0/0=[gudev] required by (media-video/cheese-3.12.2::gentoo, installed)
    virtual/udev:0/0=[gudev] required by (x11-misc/colord-1.2.1::gentoo, installed)

  (virtual/udev-215::gentoo, ebuild scheduled for merge) pulled in by
    =virtual/udev-215 required by (games-util/xboxdrv-0.8.5-r1::gentoo, installed)
    (and 22 more with the same problem)
