Apple's Xcode does not include a fortran compiler. If you'd like to build 
Octave's sources, you'll need to install a version of gcc that does include 
gfortran. I highly recommend you either use the AT&T Research's gfortran that 
has been patched to work with Apple's gcc 4.2 ...

... or, use a package management system like Fink, MacPorts, or Homebrew.

        http://www.macports.org/

        http://mxcl.github.com/homebrew/

If you're not sure, I recommend a package management system over installing the 
patched gfortran from AT&T Research's gfortran. I've used both Fink and 
MacPorts. I have no problem building the developers sources with MacPorts, but 
have some trouble with Fink. Homebrew looks like it would be easy to build 
octave with, but I haven't tried.
