I have now fixed the regex problem that was screwing up detection of 2.9.x 
(where x is a single digit) so please try again.  Hazen has reported that
octave (version 2.1.xx) works for him on Mac OS X so it's likely the regex
fix will be all you need.

The problem with octave-config is that the list of -p options changes rather
drastically with octave version so queries to octave-config for build
information must be version specific.  That's a real PIA so I have given up
on octave-config.

Another possibility (see my previous post about this) is to use the
"mkoctfile" command (essentially an independent platform-specific octave
build system) within our build system.  That's the approach we use with our
ABS, but I never liked it particularly since it means there is a foreign
build system within our build system (either CBS or ABS) so you have to deal
with the union of the bugs for both build systems.  So far (except for minor
problems such as the version number) the current simplified linking approach
I am using to build the octave interface to PLplot is working both on the
Linux (Debian stable and Ubuntu Dapper with results still to come from
Orion on Fedora) and Mac OS X platforms (at least for Hazen), but if we
run into a showstopper problem with that approach as we extend testing to
other platforms, I am mentally prepared to fall back to mkoctfile.
