[Boost-users] Embedded Python issue

Hello,
I am trying to run some embedded Python code, following the boost.Python 
tutorial.  What I was hoping to do was import some external modules.  So 
basically in my .cpp file I have:

    Py_Initialize();

    object main_module((
            handle<>(borrowed(PyImport_AddModule("__main__")))));
    object main_namespace = main_module.attr("__dict__");

    try{
    handle<> ignored((PyRun_String(  "import Numeric\n"
                                     // Other Python commands
                  , Py_file_input
                  , main_namespace.ptr()
                  , main_namespace.ptr())
));
    }
    catch(error_already_set)
      {
    PyErr_Print();
      }

    // Finish the Python Interpreter
    Py_Finalize();

However when I 'import Numeric', I get an undefined symbol:
Traceback (most recent call last):
  File "<string>", line 4, in ?
  File 
"/afs/nd.edu/user25/tcickovs/Research/PYTHON/lib/python2.4/site-packages/Numeric/Numeric.py", 
line 91, in ?
    import multiarray
ImportError: 
/afs/nd.edu/user25/tcickovs/Research/PYTHON/lib/python2.4/site-packages/Numeric/multiarray.so: 
undefined symbol: PyExc_ValueError

Now if I just run python from the command line and call 'import Numeric' 
everything is fine.  Does anyone have any idea what I need to do 
differently if I use Boost?

Thanks for the help,
Trevor
