Argh. Yep, you're right - I shouldn't try to answer technical
questions when I'm that tired.
The grep was still a good starting point because it indicates that
the kvm_* entities should be coming from a system library. So the
next step is:
nm --print-file-name /usr/lib/lib*.so /usr/lib/lib*.a \
2>/dev/null | grep '[Td] kvm_'
This shows that they are in, unsurprisingly, libkvm.a and libkvm_p.a.
So the link for FreeBSD is missing '-lkvm'. (Or, possibly, has it
too early in the list.)
I still don't know where auto_nlist is supposed to be coming from.
Grepping through the source and examining the code around references
might give a clue based on what it appears to be doing.
