If he is, that would make sense.

In the port you unconditionally set:

set stage0(distfile)        [join "rust stage0 ${stage0(date)} ${stage0(rev)}
                                ${stage0(platform)} ${stage0(hash)}" -].tar.bz2

But ${stage0(hash)} is only set in a platform darwin block. That means indexing the port will fail on our server as well. Which explains why rust is missing from the online list of ports:

http://www.macports.org/ports.php?by=name&substr=rust

Anyway, the port already claims to require OS X 10.6 or later, so Bill, you won't be able to install this on 10.4. Still, we should fix the port so it at least always parses.
