What's the output if you insert a call to PyErr_Print on the line  
that start with "if(!myMod)" (e.g.:
         if(!myMod) { printf("cannot import StringModule wave\n");  
PyErr_Print(); return TRUE; }

Please use the version in my zipfile and run 'make' to build and run  
the ScriptSupport program.
