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*.?_*
