Portage uses the metadata cached slot when doing dep resolution, so it
goes spectacularly wrong.

So what's the slot when SLOT="foo? ( 1 ) bar? ( 2 )"? And should you be
able to have the same KDE version with both USE=multislot and
USE=-multislot installed at the same time?

Unfortunately, the issue's not as simple as allowing conditionals in
SLOT in a future EAPI.
