I think that would be a bad thing.  I sometimes build Octave on
systems where I don't have gnuplot installed.  It would be annoying if
I couldn't finish the configure step without first installing gnuplot,
which I'm unlikely to use on those systems anyway (I'm just testing
the Octave build).  OTOH, I suppose we could offer a --without-gnuplot
option similar to the --without-readline option.

The gset and other gXXX commands are going away in Octave 3.0.

If I'm making publication quality graphs, I usually write out data
files and then use gnuplot directly.  I also usually use Make to drive
the whole process of generating data and making plots.  That way, the
rendering of the plot is separated from the generation of data.
Modifying the plot doesn't require repeating the calculation, which
might take a long time to do.
