Python extensions on OS X are built as bundles, and are expected to be
loaded dynamically by Python or another program that is linked to the
Python framework. The extension expects to find all the Python
symbols already loaded.
SIP gets the -bundle flag right, but also links directly to the Python
framework.
The nice benefit of this is that we can compile an extension with one
build of Python (say the Leopard system Python 2.5.1), then install a
newer (point version) Python and have the extension loadable in the
newer Python. Or distribute the extension where others might have
installed a newer version of Python.
This will take care of not-linking the python framework - in
siputils.py, ModuleMakefile().finalise(), change:
self.LFLAGS.append("-F%s" % string.join(dl, os.sep))
self.LFLAGS.append("-framework Python")
to:
self.LFLAGS.append("-undefined dynamic_lookup")
