Hmmm, as far as I know, you don't need to install anything extra if you
already have/use GDAL tools _and_ Python in your system.

Information (that should be) of your interest:
http://wiki.osgeo.org/wiki/OSGeo_Python_Library
http://trac.osgeo.org/gdal/wiki/GdalOgrInPython
http://grass.osgeo.org/wiki/GRASS_and_Python
