However, I would suggest to run it with the flag --log DEBUG, so that a logfile ($HOME/fred.log) is created, and you can try to figerout what happens if . This log file is very useful when FRED crashes or does not want to run. Besides that logfile, a directory $HOME/.fred with is created and contains other logfiles are created. But those ones did not help me when FRED was not working due to configuration errors...
You can use the simple script myfred (from csh or tcsh) as an example of how to run the fred version you want (in debug mode) with the ruby package you want.
FRED will be acting as a client of Gleam which will be the engine processing the events.
The configuration of the execution of Gleam is performed via the FRED GLAST pannel.
