Good, no grads related environment variable is being set, so we can rule
out any conflict there.

Either is fine, provided the whole Contets/ directory (and all
sub-directories are moved over). In your case, make sure /opt/opengrads  is
ahead in your path (and not another directory further down under Linux/).

Sometimes you need the -X option to enable X windows through ssh, for
example

% ssh -X myserver.domain.com

You can run grads interatively without having X Windows connecivity. Just
start opengrads in batch mode (-b option) :

% opengrads -bl

What I am looking for is whether you see a line like this:

*Loading User Defined Extensions table
</Applications/OpenGrADS/Darwin/Versions/2.0.0.oga.1/i386/gex/udxt> ... ok.*

and whether

ga-> q udx

gives you a full list of extensions.
