I commented this out in the fgs-dev that i've been messing around with,
i wasn't sure what is was doing and i think i was having problems
getting gdal to build properly with it.

I've had the same problem with the packages finding dependencies outside
of the fgs-dev environment.  what i ended up doing was using a virtual
machine for fgs-dev and minimizing what's on the system
