A quick look at how to install gdal lead to scary pages, and a requirement to install GEOS, etc.

Looking at tests/gis_tests/models.py, it looks like it's trying to neuter itself if the GIS requirements aren't installed, but I guess it isn't doing it well enough?

I'd be glad to hack on making this better if someone could guide me on the philosophy to follow."	Cleanup/optimization	closed	Testing framework	dev	Normal	fixed			Accepted	0	0	0	0	0	0
