This is the traditional Squeak VM, which is useful for Squeak images
up through Squeak 4.6. This VM is hosted at http://squeakvm.org.
Newer and current Squeak images use the opensmalltalk-vm VM, which
is hosted at https://github.com/OpenSmalltalk/opensmalltalk-vm.

Recently we had some work under way to update the Debian distribution,
which currently has only the older traditional Squeak VM, so that
the installed VMs on Debian would include both the older and newer
VMs. This would enable users to run various Squeak images without
worrying about what VM to select. The work is incomplete and I
don't know if it will ever be finished, but the basic package
strategy would presumably be similar for RH and Debian.

I am attaching a script that you can use to pull the latest sources
for the traditional VM, and create a source tarball. This is the
tarball that we were using for the Debian package update (unfinished)
and it would give you a set of up to date sources that would
probably be suitable for RH also. You will need to install Subversion,
then just run the script in a clean directory to produce the source
tar Squeak-4.19.15-3822-src.tar.gz.

For reference, the script comes from the Subversion repository at
http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/trunk/platforms/unix/cmake/mkunixtar?revision=3814&view=markup

General information on building the VM for unix is at https://wiki.squeak.org/squeak/6354.

HTH,
Dave
