Ok, but the only purpose of config.guess is to look at your system and print a string like (on my system) "x86_64-apple-darwin10.8.0". I'm not sure but I'd hope config.guess has figured out enough of how OS X works by now to be able to do that reliably even on future versions of OS X.

That would be primarily a matter to help out the upstream developers, but it doesn't look like those lines of the script are of any use to MacPorts. We want the user to be able to choose the architecture; that choice is expressed as the build_arch variable and the reduce-algebra port should use build_arch to pick the MACHINE variable.

Can you send me your current Portfile? I'll give it a try and see what I see.
