Uh eh, this is broken in multiple ways in all versions... :/ See attachment.
Created attachment 102026 [details] media-sound/bmpx broken dependencies
Note that.. - cairomm was just unmasked from package.mask, please keyword it ~ppc ~ppc64 if it isn't allready. - USE="ofa" can be masked in ppc/ppc64 profiles to avoid "libofa" borkage.. - USE="p2p" can be masked in ppc/ppc64 profile to avoid "moodriver" borkage.. And the fact that media-sound/bmpx is still on package.mask, waiting for dbus unmasking.
I think I've fixed all of the 32 bit ppc deps, re-assigning to ppc64. libofa marked ~ppc p2p masked in the hardened (ppc and ppc64) and selinux profiles as well as in the default profile.
I took care of libofa but I cannot run with this much further. I dont have ppc64 hardware capable of sound.
This bug was about broken deps which apparently are all solved now so closing it as fixed.
