I am away and cannot look at this right now, but when I last built a
Cog VM to test this I was using the configure / make procedure (not the
CMake procedure) and it seemed to be working, but maybe I was confused
or maybe there is there is some difference related to the build procedure.
Sorry, I am only guessing, and I'll try to look at it again in a couple
of days.

I think there was an issue on some of the Mac platforms that required
a compiler flag to force the compiler to make global variables visible
(for the environment vector, etc). Is that the problem here? I do not
have a Mac, but I'll try to help figure this out if I can.
