Well, ParlorBot gets its moves like this:

To gnubg: set matchid MAEtAAAAAAAA
To gnubg: set board 4HPwATDgc/ABMA
To gnubg: hint 1
From gnubg: The dice have been set to 2 and 3.
From gnubg: 
board:opp:gnubg:1:0:0:0:-2:0:0:0:0:5:0:3:0:0:0:-5:5:0:0:0:-3:0:-5:0:0:0:0:2:0:-1:2:3:2:3:1:1:1:0:1:-1:0:25:0:0:0:0:0:0:0:0
From gnubg: 
board:opp:gnubg:1:0:0:0:-2:0:0:0:0:5:0:3:0:0:0:-5:5:0:0:0:-3:0:-5:0:0:0:0:2:0:-1:2:3:2:3:1:1:1:0:1:-1:0:25:0:0:0:0:0:0:0:0

I am currently using gnubg-0.15-20050522 which came from
http://www.acepoint.de/GnuBG/sources/.  gnubg.weights,
gnubg_os0.bd.gz and gnubg_ts0.bd.gz came from the same place.
