Ok, I've an version of the Squeak VM 3.2.1 awaiting in the wings which has 64bit? file support and has been compiled under Apple's Project Builder versus CW. So I'm looking for a few good folks to kick the tires. Please email me if you can test (stress test is best).
Ok, I shipped a 3.2.1Beta1 to those who asked. If you didn't get one then email me. Only runs on OS-X right at the moment, and still quite a bit of work to do.
