I use debian with fso and when i install fso-gpsd no gpsd is installed
as dependency because it would make no sense.
Fso-gpsd IS the gpsd compatibility wrapper which does the same what gpsd
does for the client applications. So be sure not to have fso-gpsd and
gpsd installed. Both programs try to access the gps which doesn't work.

My current version of fso-gpsd in debian is 0.8-2 and my fso-frameworkd
is Both are from the official debian repository.
