Upstream closed bug report https://bugs.kde.org/show_bug.cgi?id=356204: Boudewijn Rempt 2016-02-12 20:54:31 UTC Of course. It's not a bug; pigment should be built against 0.7, and hasn't been ported to Vc 1.x yet. Couyld you please make the ebuild depend on dev-libs/vc-0.7.4?
Thanks, fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=9e2f870ebccbaa2f1e0c301bc0e739b4a44264b7
