[mod_python] ImportError on mathmodule: undefined symbol: PyFPE_jbuf

You likely have some sort of mismatch with what version of Python you
compiled mod_python with and/or which version it is running as and
what installed Python library files are being found.

What version of Python did you believe was used to compile mod_python?

Was the standard Python 2.3.X which is installed on your system?

Do you have multiple versions of Python installed on your system?
