Create a virtualenv for your django (with --no-site-packages) and activate it. Then install everything you need inside it.

No, simply make sure that the one you want to use shows up in an earlier directory in sys.path.

if wsgi in use then set the path to the desired django installation in the django.wsgi file. eg

import os
import sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
sys.path[:0] = ['/path/to/django/version/','/path/to/project/']
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

If modpython then set the path in the apache configuration file

PythonPath "['/path/to/django/version','/path/to/project'] + sys.path"
