Calculating dependencies... done!

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

sys-fs/udev:0

  (sys-fs/udev-164-r2::gentoo, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (sys-fs/udev-171-r1::gentoo, ebuild scheduled for merge) pulled in by
    >=sys-fs/udev-146[extras] required by (net-wireless/bluez-4.93::gentoo, ebuild scheduled for merge)


!!! Enabling --newuse and --update might solve this conflict.
!!! If not, it might help emerge to give a more specific suggestion.


The following mask changes are necessary to proceed:
#required by gnome-base/gnome-3.0.0, required by gnome (argument)
# /usr/portage/profiles/package.mask:
# Nirbheek Chauhan <nirbheek@gentoo.org> (10 Jun 2009)
# Several feature regressions that will make our users
# go on a witchhunt if unmasked
# * No XDMCP connection UI
# * No configuration/theming support
# * No support for auth backends other than PAM
# * Many more...
>=gnome-base/gdm-3.0.4-r1

NOTE: This --autounmask behavior can be disabled by setting
      EMERGE_DEFAULT_OPTS="--autounmask=n" in make.conf.

Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT).
