i have emerged these using x86 or ~x86 keyword (yes,yes...dont beat me :)) and they seem to work right...so marking them (and maybe newer versions if they exist) ~ppc isnt a bad idea :)
Steps to Reproduce:
Thanks for the report. I have keyworded all ebuilds except porthole which was already keyworded and xmms-nsf/xmms-spc as they don't work on ppc.
Closing as resolved.
