Re: NAB: - problem compiling with graphics...

Ah yes, nab doesn't support (yet) lablgtk2.

not sure about the error below though. i've never had to set/change any 
env vars in standard setups.

does it occur when you try to launch the nabviz-top toplevel? my guess is 
that this is not nab-specific. maybe the ocaml-beginners (yahoo groups) or 
ocaml-list (inria mailing lists) can tell you what is wrong..
