Hi Ivan,

ok, in order to double check these guidelines, I'll do the whole
build from scratch and see if they lead me to the point where you are now.
I'll have the time to do it tomorrow or wednsday, though.

In the mean time, could you try to: apply the latest Archie's patch, 
enable the assertions,
and see where jchevm exits?

Enrico
