The shorten-3.5.1 ebuild does not even have ppc listed in its KEYWORDS. After
adding PPC to KEYWORDS in the ebuild, it builds and runs successfully on my iBook.
Please enable this ebuild for PPC.
Steps to Reproduce:
1. add ppc to KEYWORDS in ebuild
2. emerge shorten
3. it works!
Thanks for testing, added to ~ppc.
Closing this bug.
