[Bug 1312507] Re: rabbitmq-server fails to start on a IPv6-Only environment

If you want to test I have a patched erlang in:

   ppa:james-page/rabbitmq

I think it forces the right behaviour in epmd:

tcp6       0      0 :::5672                 :::*                    LISTEN     
tcp6       0      0 :::4369                 :::*                    LISTEN

Bug description:
  Guys,

  I'm trying to install rabbitmq-server on Ubuntu 14.04 on a IPv6-Only
  network and it fails, look:

  ---
  root at server-1:~# apt-get -f install
  Reading package lists... Done

  After this operation, 0 B of additional disk space will be used.

   * FAILED - check /var/log/rabbitmq/startup_\{log, _err\}
     ...fail!
  invoke-rc.d: initscript rabbitmq-server, action "start" failed.
  dpkg: error processing package rabbitmq-server (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   rabbitmq-server
  E: Sub-process /usr/bin/dpkg returned an error code (1)
  ---

  The log:
  ---
  root at server-1:~# cat /var/log/rabbitmq/startup_log 
  ERROR: epmd error for host "server-1": address (cannot connect to host/port)
  ---

  The connectivity (resolved via /etc/hosts):

  ---
  root at server-1:~# ping6 server-1
  PING server-1(server-1.domain.com.br) 56 data bytes
  64 bytes from server-1.domain.com.br: icmp_seq=1 ttl=64 time=0.019 ms
  64 bytes from server-1.domain.com.br: icmp_seq=2 ttl=64 time=0.044 ms
  ---

  However, if I comment out the "nameserver 2001:4860:4860::8844"
  entries out from /etc/resolv.conf, then, rabbitmq-server starts! Very
  weird...

  Nothing on /etc/resolv.conf now...:

  root at server-1:~# apt-get -f install
