システム上に存在するIPv6アドレスが、ループバックデバイスに割り当てられた ::1 だけの場合、test/rinda/test_rinda.rb で以下のエラーが発生します。

Linux (Debian wheezy）の場合 。

当該テストを、IPv6がloopbackだけの場合はskipするように変更したいと思います。

• test/rinda/test_rinda.rb (RingIPv6#prepare_ipv6): prevent to use
  IPv6 loopback interface for
  Rinda::TestRingFinger#test_make_socket_ipv6_multicast and
  Rinda::TestRingFinger#test_make_socket_ipv6_multicast_hops.
  The tests are skipped if there are no IPv6 devices other than the
  loopback device. [Bug #11394] [ruby-dev:49199]
