After the Plasma 5 packages got moved to there new category, kde-base/kdelibs:4 got its dependency updated correctly. However, kdebase-runtime-meta:4 got missed. Adjusting the dependency locally fixes everything here. Reproducible: Always
Thanks, fixed in CVS. + 02 Jan 2015; Michael Palimaka <kensington@gentoo.org> + kdebase-runtime-meta-4.14.3.ebuild: + Update Plasma 5 compatibility dependency wrt bug #534270.
