Yo Eric!

i was going to make your suggested change.  But found that the regessions
are not working for me at all.

Processing test/daemon/ait250.log...gpsd:ERROR: device open failed: Permission 
denied - retrying read-only
gpsd:ERROR: read-only device open failed: Permission denied
gpsd:ERROR: /dev/pts/3: device activation failed.
gpsd:ERROR: device open failed: Permission denied - retrying read-only
gpsd:ERROR: read-only device open failed: Permission denied
gpsd:ERROR: /dev/pts/3: device activation failed.

Any ideas?
