 * Error: circular dependencies:

(dev-lang/python-2.7.3-r1::gentoo, ebuild scheduled for merge) depends on
 (dev-lang/tk-8.5.11::gentoo, ebuild scheduled for merge) (buildtime)
  (x11-libs/libX11-1.4.4::gentoo, ebuild scheduled for merge) (buildtime)

     (dev-lang/python-2.7.3-r1::gentoo, ebuild scheduled for merge) (buildtime)

It might be possible to break this cycle
by applying any of the following changes:
- dev-libs/libxslt-1.1.26-r3 (Change USE: -python)
- dev-lang/python-2.7.3-r1 (Change USE: -tk)
- dev-lang/python-2.7.3-r1 (Change USE: +build)

Note that this change can be reverted, once the package has been installed.

Note that the dependency graph contains a lot of cycles.
Several changes might be required to resolve all cycles.
Temporarily changing some use flag for all packages might be the better option.

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

dev-libs/libxml2:2

  (dev-libs/libxml2-2.7.8-r5::gentoo, ebuild scheduled for merge) pulled in by
    dev-libs/libxml2[python] required by (media-libs/mesa-8.0.2::gentoo, ebuild scheduled for merge)

  (dev-libs/libxml2-2.7.8-r5::gentoo, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)


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