Which GEMPAK program is the cron script calling, and what is the DEVICE being 
specified?   Are you defining $DISPLAY at the beginning of your script ( export 
DISPLAY=:0.0 )?

I would say compare the DEVICE specified for each, my guess is that the scripts 
which successfully runs from cron is using a DEVICE which does not require the 
X server.
