Various Python modules of GIS interest (those not included elsewhere, like in a framework), and other random modules. These may be available elsewhere, but usually they are built for the python.org Python, and I prefer to stick with the system Python (at least for 10.5/Leopard and above). Also, I link to my frameworks where possible. Downloads are for modules with binary components. Any others can be easily installed from source, no Xcode tools needed.
All are built for the system Python in OS X Lion (Python 2.7), Snow Leopard (Python 2.6), and some for OS X Leopard (Python 2.5). I'm sorry, but I don't support earlier versions of the system or other versions of Python, or other installations of Python (though they may work in other distributions of the same version).
Also included on the GDAL Framework disk image, though it may not be up to date.

This one has no binary components, so you can install from source without needing Xcode. Download the source, and unzip it. In a Terminal, cd to the source and:
sudo python setup.py install
