  It's absolutely necessary, after installation of the new kernel with
'options IPFW2', to add 'IPFW2=true' in /etc/make.conf and rebuild+reinstall
_at least_ /sbin/ipfw, then /usr/lib/libalias.* and /sbin/natd (which depends
on libalias), e.g.

cd /usr/src/sbin/ipfw
make obj && make depend all install
cd /usr/src/lib/libalias
make obj && make depend all install
cd /usr/src/sbin/natd
make obj && make depend all install

(note that natd doesn't depend on IPFW2, but links against libalias which
does, so sequence libalias -> natd is critical).

   I haven't found other parts of base OS in RELENG_4 which depend on IPFW2,
though I can miss something. Also every custom utility which utilizes 
<netinet/ip_fw.h> must also be recompiled with IPFW2 defined and rebuilt
(and those using libalias must be rebuilt).
