You need to find where MacOSX has their elf defs, on OpenBSD it is
elf_abi.h, and then you need to get som machdep relocs defined as
well.
i can show my kludgey current patches (not of quality i'd normally
submit, but
since you seem to be in urgent need..)
Let's hope this web form mailer does not destroy the diff. Just tell
me to resend
it from my normal mail program otherwise.
