OK, this failed on FreeBSD 8.0 for two reasons:

1. Need some include files.

-bash-4.0$ diff -up lib/tevent/tevent_kqueue.c.orig lib/tevent/tevent_kqueue.c

 struct kqueue_event_context {
        struct tevent_context *ev;


2. A weird error

[3743/3985] abi_check: bin/default/librpc/libndr.so

I don't know about this second error before. I don't think I have seen
it. Checking a build without the kqueue stuff now.
