Gnuplot is the original plotting backend to Octave; it is pretty much
built into octave, rather than being an installable package. The first
page you cite just says what I repeated above. Please take a look at the
second link to confirm that the 'gnuplot' package contains just some
scripts to output gnuplot-specific commandfiles, for offline plotting.
It is perhaps an unfortunate package name, because it invites the
misunderstanding that you fell into.
My plotting is working. I was just exploring some of the packages. And I have been running into errors when installing other packages (error: could't clean up after myself) so I thought this was related.
