gnuplot dependency in octave

I am starting a new thread on this issue.

Quoting from :

As the OP notes, having a gnuplot dependency pulls in X when installing octave,
which is not what some users need or want.  And octave will load and run just
fine without gnuplot - it just won't plot.  However, most users want to plot,
and will need gnuplot.

So, my current view is that a gnuplot dependency is optimal for most users, and
that those who don't want it can work around the issue by using known
solutions, such as hacking the /etc/setup/installed.db file to fool setup into
thinking gnuplot is installed.

On the other side is how Debian does it: gnuplot is "suggested" for octave, not
"required".  Also, Debian has a gnuplot-nox package, which I suppose omits the
gnuplot X11 drivers, and actually allows installing gnuplot without requiring

I think that gnuplot-nox is kind of a neat solution, but even if such a package
were available in cygwin, we don't have a way to express OR dependencies.  So
it would be difficult to use this approach.  Also we don't have a way to
express "suggested" rather than required.

On balance, I favor retaining the current dependency on gnuplot.  I would ask
that those with alternative views post to this thread.
