The Geospatial Data Abstraction Library (GDAL), a PyABM dependency used for handling raster and vector data) can be a pain to install, particularly on Windows and Mac systems. On Linux, I recommend installing the GDAL binary and the Python bindings to the library from your package manager. See below for sources for the GDAL binaries and Python bindings on Linux, Mac, and Windows systems.

• On Ubuntu, the UbuntuGIS team has setup a package repository that should have the latest versions of many geospatial packages.

• On Windows, I recommend using the server setup by Tamas Szekeres. You can also download the latest versions of the Python bindings to GDAL, as well as many other Python packages in both 32 bit and 64 bit versions, from Christoph Gohlke’s python extension packages page

• On a Mac, I would try using KyngChaos
