access to the mapnik Python libraries.

I would recommend first:

 1. creating a simple cgi script, which says something like:

#!/usr/bin/python
import mapnik

print "Content-Type:text/html"
print ""
print "Win!"

 2. Determining whether it works (I expect it won't)
 3. Working with the mapnik mailing list to figure out how to make it work.
    (Though I expect you'll get limited help, as this is sort of an installation
    issue, on what looks like a platform most mapnik devs don't use much.)

Best of luck.
