UPD. Building with 'qt5' flag instead of 'wxwidgets' doesn't help. Moreover, qt5 GUI is simply unusable -- buttons and menues don't work.
UPD2. Emerged the package once again, with 'qt5' flag. GUI is still unusable. Running 'dolphin-emu-nogui -e luabench.dol' doesn't segfault anymore, only shows black screen. Console output http://pastebin.com/dn1V5zKb Running 'luabench.dol' with 'dolphin-emu-qt2' also shows black screen. Console output http://pastebin.com/7gT8zBK5 Screenshot is attached.

UPD3 After settings tweaks and some unknown magic it now runs, without segfaults or something, both with bench test and games, with functional wxWidget GUI. I'm closing this bug report as resolved.
