Connected question: How do I quickly find all the packages that
got installed as a dependency, but which are no longer needed,
because the dependent package got removed (as an example, I'd
like to find kde-i18n, because that used to be a dependency of
kde-meta and kde-meta is no longer installed).
      

emerge --depclean
    

thanks. 200 some packages, which would be removed. Quite a 
lot.

After removing stuff, a revdep-rebuild should be done, shouldn't
it?

Yup :) I would also recommend removing packages by hand.....I won't go into detail, but last time I didn't do that, it took me two weeks to recover!
