Can you please test out k3b with mpg321 installed instead of mpg123. It should work unless k3b needs some of the rarely-used features of mpg123. If it works, please update the ebuilds to use virtual/mpg123. Also, kdemultimedia/kdemultimedia-3.2.0.ebuild does not have the virtual DEPEND yet, but the other ebuilds were updated. Was there a compatibility reason for this, or was it merely overlooked?
I didn't update it because I found that there's a library in kdemultimedia that seems to not get enabled to compile when using mpg321 but does when using mpg123. Since 321 should be a drop in replacement, it's probably just a bit of a trivial fix upstream, but I haven't had a chance to research it anymore than that.
should all have virtual/mpg123 now
