Download virtualenv and create a virtualenv by manually typing the
path to your Python 2.7 executable.
Something like this (path will probably be different on your Mac, type
"which python2.7" to find it:
/usr/bin/python2.7 virtualenv.py /home/user/my_virtualenv
Then activate your virtualenv:
source /home/user/my_virtualenv/bin/activate
Then you'll have your own Python environment just for this project.
You can install Django by just running "pip install django," plus any
other dependencies, without conflicts or requiring root access.

You'll just have to activate that virtualenv each time before you
start working on your project or running your app.
