The development sources have been modified to work with the Carbon framework 
for 10.5, 10.6 and 10.7 (I assume 10.8 as well).  If you're interested in the 
cutting edge, the link below provides instructions for obtaining the sources, 
and building the sources.

        http://hg.savannah.gnu.org/hgweb/octave/file/tip/etc/HACKING

Also, you may find the FLTK graphics toolkit preferable as compared to gnuplot 
(it may already be present in the version of Octave  you have).
