Darn.

Well, there is this:

http://wiki.python.org/moin/MacPython/UniversalLibrariesAndExtensions

But you're right, it would be nice to get that down to a single script. 
I'll get a start on that. Do you think it should download the tarballs 
too (curl) ?

There was some effort to put it all in a Wiki, but not really 
maintained. Also, it was suggested that folks put a README in with it. I 
did that for Matplotlib a while back, but the problem is that the 
packages are moving targets.

Another issue is that lots of Python packages rely on the same external 
libs -- libpng comes to mind. Another way to do do it would be to supply 
a standard build of those libs,a nd link all the packages against them. 
These are good options for that:

His UnixImageIO Framework is pretty handy

Exactly.
