I'd keep the virtualenv directory and the project directory completely
separate.

Keep the requirements.txt file in the top level of your Django project
and use that if you ever need to regenerate your virtualenv directory
structure. Essentially the virtualenv environment should be completely
disposable since you can regenerate it automatically in the future if
required. You certainly shouldn't be committing it a version control
system. That seems rather messy to me.
