Thanks for reporting. This is now fixed in CVS. Please sync in some hours to get the change. + 03 Aug 2012; Johannes Huber <johu@gentoo.org> kdelibs-4.9.0.ebuild: + Re-add deps that were accidentally removed wrt bug #429700. Thanks to + theodor@suremail.info. (In reply to comment #1) > Please add full build log and emerge --info. ^Never mind. Not needed anymore.
My bad. Now I remember in what way kdelibs handling is special. Still I would prefer to have this handled in eclass entirely (otherwise kdehandbookdepend needs to effectively replicated in kdelibs)
