[mod_python] Python scripts are showing source code

Hi all,

I'm new to python and mod_python and I'm trying to get a script to work on
my install of Apache.

I've installed mod_python and I can see that it's installed in the
error_log:

[Tue Apr 15 13:26:44 2008] [notice] Apache/2.2.8 (Unix) mod_ssl/2.2.8
OpenSSL/0.9.7a PHP/5.2.5 mod_python/3.3.1 Python/2.3.4 configured --
resuming normal operations

I have added LoadModule python_module modules/mod_python.so in httpd.conf

As well as AddHandler mod_python .py

The script I'm trying to run is in the cgi-bin for apache,
/usr/local/apache2/cgi-bin/, this is also setup with ScriptAlias as per the
default httpd.conf.

I'm running Apache 2.2.8 on Redhat Enterprise Linux 4. Apache is installed
from source, python and python-devel from rpm.

No matter what I do I still see the source code of the py file rather than
it running.

Can anyone help?
Thanks
Nick
