if i got it right then packaging the dependencies as seperate packages
isn't an option for zope2.12, we'll have to include them within the
zope2.10 source tarball. the reason for that is, that zope2.12 requires
particular versions of the dependencies, and doesn't build even if minor
versions aren't correct.
I do not want to wait with the removal of python2.4 from unstable
for too long, I think a short time without zope2.x in unstable is
ok, while having three python2.x versions is too much. But it looks
like zope2.12 based on python2.5 or python2.6 is doable for squeeze.
i didn't know that packaging zope2.12 is that timeconsuming at the time
that i proposed to wait with removing python2.4 from unstable. so no
objections against removal of pyhton2.4/zope2.10/zope2.11 from my side
any longer.
