Are you doing exactly the same thing on OS-X and Linux? Are you using 
distutils to compile your *.so? If so, it should work.

The differences, as far as this is concerned, are:

* that OS-X requires different flags and what not for compiling and linking -- 
distutils should take care of that for you

* Any GUI program needs to be run from inside an application bundle. This is 
true for pure C / C++ programs as well. For Python, pythonw does that for 
you.

This makes it sound like you are doing more than trying to get an extension 
that works on Linux to work on the mac. Yes, extensions can only recieve and 
return PyObjects to/from Python code, but inside your extension you jsut 
write regular old C.

SWIG is one way to generate code that translates C types into PyObjects. You 
can also do it by hand (or use pyrex, Boost::python, SIP, etc.).

I've used it on Linux only, but it certainly works on OS-X. wxPython is built 
with it, for a large-scale example!

post that example, if we are to help you, that's exactly what we need, a 
simple example. And post exactly what you did to compile it!
