virtualenv

My current setup is Python 2.5/ Django 1.1.1 on Windows. I want to start using Django 1.2 on some projects, but can't use it for everything. Which is just the sort of thing I've got virtualenv for. However, I'm running into a problem I've never encountered and it's hard to Google for: installing Django 1.2 into a virtualenv has no effect for me. If I then activate the environment and do

python
import django
django.VERSION

I get "1.1.1 Final". Django is installed in the site-packages directory of my environment and the init file in the root shows that it is 1.2. But the environment falls back to 1.1.1, even if I create the environment with the --no-site-packages flag. What am I screwing up?
