This is pretty much what happened. I've finished removing all the
packages that depclean wanted me to and things look good now.
revdep-rebuild is happy. emerge -DuN world is happy. --depclean says
there is nothing to clean out.

It seems that maybe over time some of the packages higher up have had
USE flags added to them. Maybe the old package didn't make a function
prunable with a flag so the library got installed and later the flag
was added to prune it out but the new emerge only upgraded the package
and didn't remove the libraries that were no longer needed.

At least hat's the best I can figure out.

Everything is clean now. thanks for the help!

Cheers,
Mark

Happy 2007. Off to have a beer.
