Let me know if I can help. Attached is a script for building the VM from
latest SVN sources (the install step is commented out).
Choosing the image might be harder. ckformat can be used to select a VM
for an image, but the interpreter VM can only run a V3 image (not Spur),
so maybe the comparison is not so meaningful. I have been maintaining a V3
mirror of Squeak trunk (http://build.squeak.org/job/FollowTrunkOnOldV3Image/)
but I will not be maintaining long term (only a few more months or so).
On balance, maybe it is better to use a Stack interpreter VM as the baseline.
This should be similar enough to the context interpreter VM, and it will
run Spur images, so that may be good as a baseline. It would have been nice
to say that "Cog is X times faster than the original interpreter VM" but
comparing to StackInterpreter may be close enough.
