This is a bit more in-depth than I usually get with ports. After all we're not really here to make software compile on Mac OS X; we're here to take software that compiles on Mac OS X and package it nicely. If the development version of octave doesn't compile on Mac OS X without a few easy pokes and prods, it may be time to report that to the developers and let them fix it.
