Are you really sure that you want this? I doubt that this is supported 
on OS X: on OS X, there are two kinds of files: shared libraries (with 
.dylib extension) and loadable modules or bundles (usually with .so 
extension but officially with .bundle extension).

C extensions for Python are compiled as a loadable module and I don't 
think you can link against these. See 
http://stackoverflow.com/questions/2339679/what-are-the-differences-between-so-and-dylib-on-osx

Some details in the above might be wrong, but I remember running into 
this issue in some early version of cysignals.
