Comment (by fbissey):
Ok this is how libcsage is being built on OS X, note that distutils
doesn't think it is any different from the other extensions and there lie
our problem

I also note that two .cpp files are compiled with gcc rather than g++
while the final linking is done by g++. The "-bundle" added for python
extensions is our problem, we could try to over-ride it by adding "-dylib"
on OS X.
