This has been partially resolved.  Pantxo pointed out that I needed to 
"./run-octave -cli" instead of "./run-octave --no-gui" to get the command line 
interface.  Using the "-cli" option results in a functional FLTK toolkit on 
MacOS X.  However, there is still no functional OpenGL toolkit available for 
the GUI on MacOS X.
