In case anyone is having the same problem as I had, I've discovered that
the Makefile for src/usr.sbin/xntp/xntpd needs to have the following line
inserted:

	LDADD+= -lkvm

Without including libkvm, the linker gets several _kvm_xxx undefined
symbols.

(And, in case it's a port-specific problem, this is on the mac68k port!)
