It's not that hard, I don't think. E.g., All GPL repositories live in this /gpl/ directory; it gets tarballed and gzipped and dumped into the /other/ location immediately prior to creating the build image. Maybe Apple's got some whacked-out approach to code management brought on by some funky OS Classic approach, but I doubt it, they are smart people over there.
