Well, funny is: staring rpcbind with options "-h 192.168.xxx.xxx -l -s -W" does not make
the rpcbind trying to create an IPv6 socket - which it fails due to absence of IPv6 in
kernel, but only "-h 192.168.xxx.xxx" does!

I can reproduce this weird behaviour on several CURRENT systems on which IPv6 is disabled
by default.
