Hmm.  I too get that error on Windows:

ruby -v -rsocket -e "p Socket.getnameinfo(Socket.pack_sockaddr_in(0, '208.77.188.166'))"
ruby 1.8.4 (2005-12-24) [i386-mswin32]
-e:1:in `getnameinfo': getnameinfo: address family for hostname not supported. (SocketError)
        from -e:1

ruby19 -v -rsocket -e "p Socket.getnameinfo(Socket.pack_sockaddr_in(0, '208.77.188.166'))"
ruby 1.9.1p129 (2009-05-12) [i386-mswin32_71]
-e:1:in `getnameinfo': getnameinfo: The requested name is valid and was found in the database,
but it does not have the correct associated data being resolved for.  (SocketError)
        from -e:1:in `<main>'


However it works on Linux:

ruby -v -rsocket -e "p Socket.getnameinfo(Socket.pack_sockaddr_in(0, '208.77.188.166'))"
ruby 1.8.6 (2008-07-17 patchlevel 279) [x86_64-linux]
["www.example.com", "0"]


Hmm... dunno... :(
