Details:

During installation, the command


../../run-octave -q -H -p . --eval "geometryimages ('voronoi', 'eps');"


is executed, with geometryimages.m containing the line


graphics_toolkit ("gnuplot");


At that point I had no gnuplot installed, so the installation stalled at this
point:


make[3]: Entering directory `/usr/src/octave/doc/interpreter'
../../run-octave -f -q -H -p . --eval "geometryimages ('voronoi', 'eps');"
sh: gnuplot: not found

To me it seems that


graphics_toolkit ("gnuplot");


should have exited with error already.
