I see.

I did, and from the things I tried everything is well.
Only thing is, I downloaded the latest Debian sources of octave 2.9,
applied the patch and installed it. Then, I also downloaded and
installed the latest octave-forge 2.9. For some reason, octave 2.9 does
not see the octave-forge functions. I had to add an explicit
addpath (genpath ("/usr/share/octave/site/api-v21"));
at the end of /etc/octave2.9.conf
Thank you for writing and maintaining Octave.
