I had this same problem once, and did this workaround:

#define PYTHON_DIR "..."

static const char pypath[] =
"import sys\n"
"sys.path.append(\"" PYTHON_DIR "\")\n";

...

    Py_Initialize();


    m = PyImport_AddModule("__main__");
    globals = PyModule_GetDict(m);


    res = PyRun_String(pypath, Py_file_input, globals, globals);
    if (!res) {
        PyErr_Print();
        return -1;
    } else
        Py_DECREF(res);
