Re: problem with gnuplot/aquaterm invocation from /usr/local version of octave.

[Owen Densmore]

Thanks Vic, that's useful to know.  My system is an intel MacBook  
Pro, using the latest Tiger, with GnuPlot Version 4.2, Terminal set  
to "aqua", and Octave, version 2.9.9 (i386-apple-darwin8.9.1).

So it sounds like our most obvious difference is PPC vs Intel.

Grasping at straws, here are some possible other differences:
    - I have no .gnuplot or .octaverc files.
    - Ditto for environment variables for either system.

Thank you for the calibration!
