First step in porting MacPython modules to OSX/unix: break all references between modules except for the obj_New() and obj_Convert() routines, the PyArg_Parse and Py_BuildValue helpers. And these can now be vectored through glue routines (by defining USE_TOOLBOX_OBJECT_GLUE) which will do the necessary imports, whereupon the module's init routine will tell the glue routine about the real conversion routine address and everything is fine again.
