I'd still like to know how to make distutils do this right...anyone?

yes, it is a no-no. It is assumed that foo.so will contain an initfoo() 
function to initialize the module.

What is MacPython vs. darwin Python? There is now one, unified python. 
You can use 2.3.* or 2.4.*, but either way, it's native OS-X. If you 
want to run it under classic (or on an old pre-OS-X machine), then you 
are talking a different beast, and you're not going to get it with gcc 
under OS-X. gcc only knows how to make mach-o binaries. You'll need CFM 
binaries. Your best bet is probably code warrior, which I don't think is 
supported in any way, shape or form by distutils. I used to compile 
python extensions with Code Warrior, and it wasn't too hard. Just the 
usual struggle to include and link all the right files. I think MPW can 
do it too, but I've never tried that.

Now I know why you were looking at those old docs at the beginning of 
this adventure!

Do you really need to run this under Classic?
