Well, not really. Though in the recent fix there seems to have come up another issue with build vs. Runtime dependencies.
The issue boils down to having a if RDEPEND="null" check, then set RDEPEND=DEPEND. However, the kde eclass does some inherited magic on RDEPEND, so it isn't set to NULL as supposed, which means that RDEPEND will not inherit DEPEND flags. The fix is to simply add RDEPEND=DEPEND in all kde followpackages, and the problem will go away.
However, right now, KDE doesn't depend on QT. *G*
Update Seems that this was partially an old DEPEND problem, and more importantly the fact that the KDE team updated all their packages with corrected values, but never updated the revisions. In this result, the old packages still didn't have the right dependencies, whereas parts of the new ones did. yeeey.
And it seems I have finally killed that darn thread
Good riddance, hope I won't see it again in six months.
