the math module above is failing to load because of: "undefined
symbol: PyExc_ValueError"
You may have to import some other module before loading math.
Try doing nm on libraries in /usr/lib/python2.5/lib-dynload & see
which one has this symbol (a function) in defined state ("T").
Also, verify if your script works fine out of the C program - may be
at python prompt.
