[gentoo-alt] regarding python libffi

[Markus Duft]

Hey!

since some time, libffi is removed from python. either of one things
would have been cool:

a) inserting the rm -fr _after_ patching, so that patches don't break.
   i don't even ask you to check whether patches still apply ...
b) revbumping, so that i at least see the problem immediately, not
   at the _next_ revbump, which is prolly unrelated.

at first i was really puzzeled as to why my older prefixes all break on
python updates (as opposed to more current ones, which have the python
from before the rm -fr was inserted).

Cheers, Markus
