It is wrong because WSGIPythonHome is not meant to be set to the name of the Python binary. http://code.google.com/p/modwsgi/wiki/VirtualEnvironments It is meant to be set to the value of sys.prefix for that Python installation. This is only needed if want to refer to a Python installation in a non standard location, or if using a virtual environment. So, if using your Python virtual environment it must be: WSGIPythonHome /home/alan/python/virtualenvs/py273ucs2 You cannot list WSGIPythonHome more than once and you cannot go switching it back to point explicitly, or let it default back to the system wide Python. Especially in your case because the Linux distro have hacked the system wide Python to be incompatible with your self compiled Python installation. A mod_wsgi.so file, even though compiled for 2.7, cannot be used with both your 2.7.2 and 2.7.3 installations. So, you cannot support both Python 2.7.2 (system wide) and 2.7.3 (virtual environment) on the same Apache without also changing the mod_wsgi.so file to an appropriately compiled one, in addition to commenting/uncommenting the different configurations. If you do switch mod_wsgi.so back to one compiled against system wide Python, simply do not set WSGIPythonHome.
