Created attachment 484936 [details] build.log I'm trying to compile with gcc-5.4.0-r3. If I remove *either* qt4 or qt5 from USE, the package builds and installs fine.

If I change the ebuild like it was done for the same error for media-sound/mixxx (https://bugs.gentoo.org/show_bug.cgi?id=590690 , https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4cf05fe4fe0741874905961f5ff6a4da5b4d77b1), then it compiles and runs fine.
I found out it's actually a duplicate for https://bugs.gentoo.org/show_bug.cgi?id=623178 . Sorry about that. (#623178 would better mention qt4 and qt5 in its description.) *** This bug has been marked as a duplicate of bug 623178 ***
