Philip, So basically you are saying that mapnik works on the command line but when using within Apache you get and 'ImportError' when running `import mapnik` ?
I would assume that this is because Apache runs as a different user (at least it does on unix, no idea on windows) and does not have the same environment settings (PYTHONPATH) that you set when you installed mapnik initially. So, you would either need to make the PYTHONPATH="C:\Program Files (x86)\mapnik-0.7.1\python\2.6\site-packages" at a system level (so Apache would pick it up) or set it use mod_python or mod_wsgi's methods (which one are you using?). One gocha - you are on a 64 bit machine, but is Apache running 64 bit or 32?
