Silly me, I just realised that Octave's bwlabel is an oct file, not an
m-file. So you grabbed some bwlabel file from somewhere, not from
Octave Forge's image package, and it doesn't work with Octave. Is that
Matlab's bwlabel? It looks like you're using Mac OS X, is that right?
Did you attempt to do "pkg install image-1.0.14.tar.gz" from Octave?
Did it fail to compile?

I'm not sure what's the easiest way to get the Octave-Forge packages
installed on Mac OS X. They me be already packaged by Fink or Macports
or one of those, but I doubt it. Try to install it as described above
and see how far along we get.
