OK, I tired again with current octave cvs (with your functions already
in cvs) and the script works fine with gnuplot 4.2.2, wxt & x11, no
problems at all.
My previous reported errors might be because I used the installed
version of octave instead of the cvs version -- i.e. I forgot to run
octave with "./run-octave" but used "octave" instead. I'm not sure,
but it works now so it doesn't really matter

sorry for the confusion,
