Any recent VMMaker (trunk version, not oscog) will do. For that matter,
the source distributions on squeakvm.org/unix would work because it's
just a compile time option, but some of the plugins are not updated
to work when compiled 64-bit so it's a lot easier to generate the
sources you want out of VMMaker.
