Oh dear, I suspect we may have some confusion here. Craig says:

Noah, what platform sources did you start with? The VM that Craig
describes would have been compiled with platform sources from the
trunk VM (not branches/Cog). Those sources are at:

  http://squeakvm.org/svn/squeak/trunk 

You would need to use a version of those sources from the early 2011
time frame. But I would suggest very stongly that you get an exact
copy of sources from Craig so that you are starting from exactly the
same code base that he is using (or maybe that's what you meant in your
question to Craig the about gitorious tree).

Mixing generated source code from VMMaker trunk (e.g. VMMaker-dtl.237)
with platform sources from branches/Cog will definitely not work.
And mixing generated sources (from VMMaker) with platform sources
(from Subversion) that are not from the same general time frame will
probably not work.
