You could check out 
http://www.cs.pdx.edu/~sanseri/kaffe/k2.html#Section%203.1 for an older 
(but still pretty much intact, afaict) overview of how things break 
down, assuming you're debugging the arm jit.

In that case, I'd recommend getting the (slow but useful for debugging 
ports) interpreter to work fine first, using --with-engine=intrp in 
configure. See http://egp.free.fr/oldsite/port-kaffe/port-kaffe-0.2.html 
for Edouard's notes on his alpha port.
