I am referring specifically to an interpreter VM that you might build from the
latest updated sources according to this recipe:

  http://wiki.squeak.org/squeak/6354

That is not very helpful if you are on a Mac, sorry for that. I think that
it may work on Mac if you have the X11 support installed, but I am not in
a position to verify it.

The squeakvm.org site is getting out of date, although Ian Piumarta said
in private email that he would welcome constructive input to bring it up
to date, and possibly to update the interpreter VM builds if there is some
general interest in doing so.
