How do set Python path to run Django with WSGI and Apache?
You need to build mod_wsgi against python 2.7 and load this module into apache instead of the current mod_wsgi version you are using that links against python 2.4.
This requires root access to the machine.
The default Python on the server is 2.4, but Django needs version 2.5 or higher. So I installed Python 2.7 in different directory and trying to run Apache with WSGI. 
Now, how do I specify for Apache/WSGI to use Python 2.7 to run the Django project?
[edit]
I can't update Python 2.4 because CentOS depends on that version of Python. Unless there is a safe way of updating without breaking a service such as yum
