I don't disagree, but I don't think that "Without this change, or somethi=
ng=20
functionally equivalent, the Octave bindings are unusable."  is accurate,=
 as=20
you said in another e-mail. Indeed, plplot_octave_path is only used by=20
use_plplot, which is buggy and don't work.

Also you might want to know that octave-plplot does not depends by itself=
 on=20
octave-2.1, as Alan makes its testing with octave-2.0.16 and promptly rep=
orts=20
incompatibilities he founds and that I'm happy to fix.
Does Debian-stable use the octave-2.1 series? I think that RH-8.0 uses=20
octave-2.1.3?. Suse-8.1 don't has octave! (but suse-8.0 had 2.0.16).

As you have expertise that I lack, could you comment on the following set=
up to=20
avoid rebuilding the .o file whenever a  "make install" or plain make com=
mand=20
is issued?
This works for both octave-2.1.36 and 2.0.16. Remember that mkoctfile-2.0=
=2E16=20
does not supports the -c option.

plplot_octave.oct: plplot_octave.o

# this compiles (slow) and links, generating .o and .oct,
# but links with the wrong LD_RUN_PATH (doesn't matter)
