Point Django at different Python version
You have it backwards.
Django is added to Python's environment.
When you install a new Python, you must reinstall everything -- including Django -- for the new Python.
Once you have the new Django in the new Python, your PATH settings determine which Python you're using.  
The version of Python (and the PYTHONPATH) determine which Django you'll use.
Django application requires a later version of Python. I just installed it to 2.5 (from 2.4) and now when I do a python at the command line, it says 2.5.2. 
Having said that, Django still says Python Version: 2.4.3. 
How do I correct this? I've rebooted / restarted / redeployed to no avail.
