!!! '=kde-base/kcontrol-3.5.2USE="ssl-arts-debug-ieee1394-kdeenablefinal-kdehiddenvisibility-logitech-mouse-opengl-xinerama"' is not a valid package atom.

Result is not OK, you have following choices:
- if emerge failed during build, fix the problems and re-run revdep-rebuild
    or
- use -X or --package-names as first argument (try to rebuild package, not exact
  ebuild - ignores SLOT!)
    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)
