sys-apps/most is marked as -ppc. The ChangeLog comment indicates: 21 Jul 2002; Mark Guertin <gerk@gentoo.org>: updated keywords (-ppc), this relies on x86 objects This isn't actually the case, it's just that the Makefile does really stupid^W idiosyncratic things regarding object directory names. The newly committed 4.9.5 ebuild works on x86, amd64, sparc and mips, so I'm pretty sure that the only reason it's -ppc is the misleading "x86objs" directory name. You'll probably need to add a few lines to src_install to tell it where to look for binaries. The code definitely isn't x86-specific, though.
Thanks for the heads up. I added ppcobjs, tested it and keyworded.
