Sorry, I've missed this when doing initial testing. Fix or remove USE slang from games-emulation/advancemame. Quoting from http://bugs.gentoo.org/show_bug.cgi?id=209416#c20 <quote> Since slang is not slotted anymore but e.g. advancemame still depends on =sys-libs/slang-1*, there are now incompatible dependencies pulled in on an x86 system since slang-2* is stable (if advancemame is installed). </quote>
gone.
