Ralf,

Thanks for doing all this!

It sure would be nice to clean that up.

 For OS X we need two different machines, because we still

Adding 2.6 is not a huge deal, but I agree -- what's the point? And it
really is time to drop PPC an 10.5, though I'd be interested to see if
anyone IS still using it.

haven't tried it yet, but it should be doable -- if a pain and a laudable goal.

nope -- good plan.

Note that I am trying to unify some of this binary building -- the
same techniques used for matplotlib and useful for other packages, too
(numpy/scipy for sure), but also PIL, netCDF, who knows what?

I'll post here when I get a little further and there is something for
others to look at and/or contribute to.
