I doubt anyones tried your setup before.
You might try running the exec line by hand
(make sure that $PERL is correctly set and runs correctly).
OTOH, the error message indicates some other problem...
maybe something about your setup makes the test suite get
confused about which directory it's in.

There is no "correct" way, but can more-or-less use raw2gp rather than
raw2xp.  (But they're not guaranteed to be completely compatbile.)

Yes, ~ns-2/bin/raw2gp (takes all.tr => gnuplot).
