Unresolved symbols against stock kernel

[softwatch]

I've been using the RPM version of MOL on YDL 2.3 with no problems.
I'm now trying to use the dev branch. I followed the instruction, seached
the list and tried eveything I can think of, but I still get a list of
unresolved symbols (misc_deregister, handle_mm_fault, force_sig...) when
trying to load MOL. I want to have a binary running with the stock kernel
(2.4.20-8d) like the RPM does.
Is it a problem with the kernel sources? Any idea how to fix that?

TIA
