Download the latest Django from http://www.djangoproject.com/. As I write this, the latest release is 1.1.1. Download it; it will be Django-1.1.1.tar.gz. Use ‘gunzip’ to decompress it; then use tar -xvf to dearchive it. You can also just double-click it in Mac OS X to decompress and dearchive it.
Once you’ve got the Django-1.1.1 folder ready, you need to go to the command line. In Mac OS X, this is the Terminal app in your Utilities folder. Type ‘cd’, a space, and then the path to the Django folder (you can probably just drag and drop the folder onto the terminal window after typing ‘cd ’.
Once you’re in the Django folder in the command line, type “sudo python setup.py install”.
Django is now installed. If your administrative account is not your normal account, go back to your normal account.
