I'm just preparing the next release of Exupery. This release is just bug fixes. It's now reliable enough to play with.
Installation instructions are here:

There's a compiled VM for Linux there. Get the Squeak code from SqueakSource for now, I'll place it on SqueakMap soon.
Some feedback on the documentation here would be great:
