Comment (by kencu):

 so getting past the missing header was not hard:

 but that later led to this linkage failure anyway:

 and of course that {{{ld: illegal text-relocation}}} is a common error on
 i386 32 bit systems, but it just indicates that -- pretty sure -- nobody
 has ever built this libjit component for i386 darwin, or at least not in a
 while.
