Wow, your "lite" module is half a meg. I'd hate to see the heavy
version. :)

I may not understand the extension so please tell me if I'm off-base:
Would it be simpler to have a single setup.py and a set of flags to turn
on and off each of the "secondary" extensions?

If I did this, I would consider a different strategy. I would suggest
that each of the setup.py's could move their "setup" function into an if
__name__=="__main__" block. Then setup_all.py could import each one (a
little trickery needed there) and then combine the symbols like
sourcelist, headers, ext_modules and so forth.

I would expect to use lapack_lite.pyd. It's easy enough to override it
by copying a custom lapack on top.
