[gradsusr] Do the GrADS Examples work?

For what it's worth, I had my Graduate level class go through the entire
tutorial seamlessly less than 1 month ago.
May I recommend that you simply start over from scratch (i.e., redownload,
compile, etc.). I had some issues yesterday downloading modules from
NCAR/RAL (I know, not GrADS-related) that didn't build properly - and the
reason why it didn't work made no sense. We downloaded again, built from
scratch, and like magic, things worked out.
thank you,
matei
