This is odd.  Your loopback adapter has no IP addresses 
bound to it.  That would explain why you can't send to 
localhost, but not how it ended up in this condition.

I suspect there is something in your /etc/rc.conf that is 
preventing the default ifconfig_lo0 settings from being 
applied.  First guess: do you have network_interfaces="" set 
in /etc/rc.conf, and if so, did you forget to include lo0 in 
the list?
