I just wanted to confirm that the patch works, thank's a lot Matt!

... and relay the following repoman output:

RepoMan scours the neighborhood...
>>> Creating Manifest for /var/db/repos/gentoo/media-video/ccextractor
  inherit.deprecated            1
   media-video/ccextractor/ccextractor-0.85-r2.ebuild: line 6: please migrate from 'cmake-utils' to 'cmake'
RepoMan sez: "You're only giving me a partial QA payment?
              I'll take it this time, but I'm not happy."

I'm not familiar with cmake and simply changing the inherit to "cmake" does not work, so that's still on the todo-list then.
