I experienced a problem here as well. My take on it was that the
DHCP thing is an wart really, there is a dhcp_interfaces variable on 4.x,
which the nicer approach imho. On 4.x rc.network line 194 empties
dhcp_interfaces on 4.x, I made a pr about it, but the answer was
to use the start_if mechanism
( http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/46454 ).

On 5.x I use a small patch, which is not entirely correct but
it works for me:

+       dhcp_list="`list_net_interfaces dhcp` $dhcp_interfaces";
        if [ -z "$dhcp_list" ]; then
                return 1
        fi
