Embedded Python 2.1 and AIX

[Galen Swint]

Hello,
I'm embedding Python 2.1 in an AIX 4.3 library and it's crashing every time the
embedded Python calls for an import of the 'string' or 'math' module. With a
little bit of gdb work I can find that it's crashing with SIGSEGV in the
'initstrop' function (or 'initmath' -- take your pick) when it calls
Py_InitModule4. Apparently, when the library is linked the reference to
Py_InitModule4 is not resolved.
I placed some print statements to print the pointer value of Py_InitModule4 and
its fine the four or five times it's called until the library init calls it.
I have done the import by running the embedded Python on a file with the import
statement on, running the import statement using PyRun_SimpleString, and using
PyImport_ImportModule.
I do call Py_Initialize, and I can execute code like prints and PyDict
functions before the import calls.
Some more info
-Python configured with
    ./configure --with-threads --with-gcc --prefix=/opt/local
(also, it is loading the library from the correct directory
(/opt/local/lib/python2.1/lib-dynload) according to gdb)
- The Makefile for the test program is below
I suspect there is some linker flag omitted or something of that nature
Thanks
