You will need to use a "classic" VM to run this image, because the newer
VMs in use today are not able to run a Squeak 4.3 image.

You can find a precompiled VM for ARM v61 at http://squeakvm.org/unix/
which may work, although it is out of date so I am not sure if it will
run on your Pi.

If you do not mind installing development tools on your Raspberry Pi, then
the best thing to do is compile the VM yourself. Instructions for doing
this are at http://wiki.squeak.org/squeak/6354

If you have any difficulty building your VM, please ask for help. And
if it works without problems, please report back so we know.

Thanks,
Dave
