Unfortunately our build system isn't really kind in this regard, and
typically the answer has been "you should understand what's going into
your KERNCONF instead of having the build system automatically handle
it for you" (or at least that was the song and dance I got on
questions@ 9 years ago when I first started using FreeBSD).

It would be nice if the ipfw authors actually generated a manpage that
listed the requirements ;)...

Also, FWIW:

./ip_fw_nat.c:MODULE_DEPEND(ipfw_nat, libalias, 1, 1, 1);
