In this post, I’m assuming you followed the steps to download and install the subversion version of django as laid out in my previous post.

Start by opening the Terminal up and running the following commands:

svn up ~/Documents/django/django-trunk
sudo python ~/Documents/django/django-trunk/setup.py install

Make sure you enter your password when the process asks for it.  When it is done, you should have django updated to the latest build from the subversion trunk.
