I checked it, "-I/usr/X11R6/include" is necessary, "-Wl,-framework -Wl,OpenGL" 
can be neglected for Octave.

And I forgot to say that I also needed to compile a new freetype2 because the 
one that comes with OSX 10.4.9 is too old. Maybe this is not necessary with OSX 
10.5.2. No FLAGS necessary for the configure step of freetype2, it compiles fine.
