I solved this. Using tcpdump I saw a lot of this:
13:19:25.271573 IP6 localhost.38025 > localhost.8649: UDP, length 48
13:19:25.271591 IP6 localhost > localhost: ICMP6, destination unreachable,
unreachable port, localhost udp port 8649, length 104
So I changed `localhost` in `gmond.conf` to the ipv4 address of the
computer (192.168.1.x). The node shows up now!
