[ gpsdrive ] Continuing Run-time error

[R. G. Newbury]

I am still having a problem getting an instance of gpsdrive to run. This 
  is using a 2 day old trunk SVN pull:
cmake report that I have boost - filesystem
and postgresql is started, but obviously gets killed..!!


[root at tor4 maps]# service postgresql start
Starting postgresql service:                               [  OK  ]
[root at tor4 maps]# gpsdrive -i -p -v

WARNING: NMEA checksum test switched off!

Can anyone help?
