Strange problem with DHCPD

[Carstea Catalin]

i recently installed
net/isc-dhcp3-server<http://www.freebsd.org/cgi/url.cgi?ports/net/isc-dhcp3-server/pkg-descr>port
on my server and when i try to start the service from his script
 /usr/local/etc/rc.d/isc-dhcpd.sh start he doesn't start.
 But if i try /usr/local/sbin/dhcpd he work fine.
 Why ?
