I've written a little how-to and provided two VMs. So would some
people using Squeak on x86 Linux try to install it and let me
know how you get on. (Just download a VM and install a package off
SqueakMap).

The instructions are at:

Exupery is a compiler for Squeak. It compiles bytecodes to machine
code. Currently it's about 10% slower than VisualWorks on my machine
for the byte code benchmark. Exupery gets about 540 million
bytecodes/second and VisualWorks gets about 600 million
bytecodes/second. There is plenty of room to tune Exupery's bytecode
performance more but I'm resisting so I can work on send performance.

Have fun
