dhclient denied

[Bob Hall]

I posted about this a while ago, but I haven't been able to 
find the cause. I'm getting the following message:
Aug 21 13:00:03 kongemord dhclient: send_packet: Permission denied

DHCP seems to work fine; I'm getting and maintaining DHCP leases 
properly. But these messages are filling up my messages file and 
causing my curiosity to drive me crazy. I initially thought that 
my firewall was blocking DHCP packets, but I've tried various ipfw 
rule changes, including some suggested here, with no effect. My 
current DHCP rules are:
        ${fwcmd} add allow udp from any bootps to any bootps keep-state out via
	${oif}
        ${fwcmd} add allow udp from any 68 to 255.255.255.255 67 keep-state out
	via ${oif}
I know the second line is redundent. I was grasping at straws when I 
put it in.
 
Generally, a failed connection attempt generates a message with 
the IP address and port at each end. This message doesn't have that, 
so that and the failure of firewall changes to end the message make 
me think that the blocked packets aren't getting as far as the firewall. 

Does anybody have any idea what is causing this?
