Hmm. So this means on Snow Leopard and up, you're not using the downloaded distfile at all, really. You could dispense with downloading the distfile at all in that case.

Second, it looks like on Snow Leopard and up, you're just copying Apple-provided files into the prefix. What if Apple updates those files in a Mac OS X update or a security update or an Xcode update? Would it be better to install symlinks rather than copy the files?
