I had to mark stable getmail-4.2.5 unstable on ppc, because Rob removed some python ebuilds, and ">=dev-lang/python-2.3.3" dep is not available on stable ppc. Currently, there is no stable getmail ebuild for ppc. I suggest someone tests appropriate python ebuild and marks it stable for ppc, doing the same with getmail-4.2.5 subsequently. Actually, feel free to test getmail-4.3.1 instead, 4.2.5 is quite old by now. Thanks for your time, guys.
python-2.3.4-r1 marked ppc, thanks for the notice
