There was issues with pykde4 recently resulting in these blockers. Easiest way
out is to remove all local masks you might have for PyQt and pykde4, unmerge
both and emerge -uND world. Let portage sort it out.
IIRC you can get by by just unmerging one of them and it works. But, I'm too
lazy now to figure out which way round it goes, and memory ain't what it used
to be.
