Here is another clue.  Something seems to be wrong with the loopback:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4
        inet6 ::1 prefixlen 128
ripple# ping localhost
PING localhost (127.0.0.1): 56 data bytes
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address

I have not set up a firewall on this host, so the problem is something else, 
perhaps the output above from ifconfig helps.
