Python Configuration

System default is Python 2.5 in /usr/bin. Under SuSE, the site package location is customised to /usr/local/lib64/python2.5/site-packages with /usr/lib64/python2.5/distutils/distutils.cfg.

Application packages will be installed separately to avoid version conflicts and maintenance problems with a single package area. virtualenv or zc.buildout could achieve this. virtualenv is easy to set-up with mod_wsgi - see Apache Configuration. zc.buildout enables overriding control over package versions to define a package and version combination to make a stable deployment. zc.buildout  collective.recipe.modwsgi enables integration with mod_wsgi. zc.buildout is currently the preferred means of configuration (17/06/2009).
