I tried your code on the

amd64% uname -a
FreeBSD amd64.kiev.zoral.com.ua 6.1-RELEASE FreeBSD 6.1-RELEASE #1: Fri May 12 12:05:38 UTC 2006     root_at_:/mnt/bsd/obj/amd64/usr/bsd/src/sys/GENERIC  amd64

and did not receive any errors. Could it be that you have lo0 misconfigured ?
What ifconfig -a show ?
