Could not bind to IPv6 address

[János Csárdi-Braunstein]

If i set ipv6 address to listen_addr, pilerd can't start:

Mar 31 15:34:08 199016 piler[31045]: reloaded config: /usr/local/etc/piler.conf
Mar 31 15:34:08 199016 piler[31045]: ERR: cannot bind to port
Mar 31 15:34:08 199016 piler[31045]: piler has been terminated

ipv6 is unsupported. However I've added this request to the TODO list, and it's likely to be added in 0.1.24.
