Why not build libcore_module1.dylib as one would normally do (and I haven't done that yet, so can't help you there, -dynamiclib seems to be the right way). Then use distutils to build the extensions, that way the exentions get build how they should be. > > If I create only core_module1.so (as bundle, without dynamic > library) it > loads properly, but if I do it this way Python 'hangs' when I try > to load > module.

I suppose your script stops executing when it hits the import statement, but the quotes make me curious.
