I wasn't paying attention to the message subject. It's just that your 
problem sounded like something that might happen if one tried to build a 
dynamic library by hand using MinGW. But MinGW is strictly a Windows 
version of gcc. I know nothing about OS X dynamic libraries. But it 
still appears that the init function for the Pyrex module is not being 
exported. Is there some compiler option that exports all non-static 
functions? I did compiler your SolveSAC_Wrap example and it did load, 
but failed because I had no BMMain to import. This is the setup.py file 
I used:

from distutils.core import setup
from distutils.extension import Extension
from Pyrex.Distutils import build_ext

setup(
  name = 'SolveSAC_Wrap',
  ext_modules=[
    Extension("SolveSAC_Wrap",       ["SolveSAC_Wrap.pyx"])
    ],
  cmdclass = {'build_ext': build_ext}
)


Just execute it with:

python setup.py build_ext --inplace

I am guessing distutils uses cc on OS X.
