Configuring search environment for revdep-rebuild

Checking reverse dependencies...

Packages containing binaries and libraries broken by a package update
will be emerged.

Collecting system binaries and libraries... using existing /root/.revdep-rebuild.1_files.

Collecting complete LD_LIBRARY_PATH... using existing /root/.revdep-rebuild.2_ldpath.

Checking dynamic linking consistency... using existing /root/.revdep-rebuild.3_rebuild.

Assigning files to ebuilds... using existing /root/.revdep-rebuild.4_ebuilds.

Evaluating package order... using existing /root/.revdep-rebuild.5_order.

All prepared. Starting rebuild...
emerge --oneshot  =app-text/poppler-bindings-0.5.3 =dev-lang/python-2.4.3-r3 =dev-lang/ruby-1.8.5 =dev-libs/apr-util-0.9.12 =dev-libs/pwlib-1.10.1 =gnome-base/gconf-2.14.0 =media-libs/libquicktime-0.9.9 =media-plugins/gst-plugins-xvideo-0.8.12 =media-plugins/libvisual-plugins-0.4.0 =media-video/kaffeine-0.8.1-r1 =net-dns/avahi-0.6.12 =sys-devel/gcc-4.1.1 =x11-wm/compiz-quinnstorm-0.0.13.43

Calculating dependencies -
emerge: there are no ebuilds to satisfy "=media-video/kaffeine-0.8.1-r1".


revdep-rebuild failed to emerge all packages
you have the following choices:

- if emerge failed during the build, fix the problems and re-run revdep-rebuild
    or
- use -X or --package-names as first argument (trys to rebuild package, not exact
  ebuild)
    or
- set ACCEPT_KEYWORDS="~<your platform>" and/or /etc/portage/package.unmask
  (and remove /root/.revdep-rebuild.5_order to be evaluated again)
    or
- modify the above emerge command and run it manually
    or
- compile or unmerge unsatisfied packages manually, remove temporary files and
  try again (you can edit package/ebuild list first)

To remove temporary files, please run:
rm /root/.revdep-rebuild*.?_*
localhost ~ # emerge kaffeine
Calculating dependencies
!!! All ebuilds that could satisfy "kaffeine" have been masked.
!!! One of the following masked packages is required to complete your request:
- media-video/kaffeine-0.8.2-r1 (masked by: package.mask)
- media-video/kaffeine-0.7.1-r2 (masked by: package.mask)

For more information, see MASKED PACKAGES section in the emerge man page or
refer to the Gentoo Handbook.
