Comment:

 Whomever has time to commit all the new individual ports, please go for
 it.

 I'm mulling the meta port still, and welcome others' input. I think we
 might just repurpose kdegraphics4 itself to be this meta package. Let's
 hammer out the meta package idea before we stub kdegraphics4 (even though
 it won't install now anyways).
