BitNami Django Stack has been updated to include support for PostGIS and Python 2.7! While we already had this on our to-do list, feedback from several users inspired us to get it out the door earlier that planned. Thank you to everyone who took the time to let us know that they would like to see this, and please keep the feedback coming!
Note that currently, the built-in PostGIS integration is only for Linux and Mac OS X. You can manually install it on Windows (take a look at this). You may also want to check out our PostGIS Quick Start guide.
