OK, this can either mean that named isn't running or isn't listening
on the 127.0.0.1 interface (/var/log/messages should tell you if
it started up and bound to that interface), or it could mean
that you aren't able to contact the root servers.

If the server is running, then you either need to make sure that
udp and tcp, port 53 can get to the internet and back with
appropriate NATting, or you have to add forwarding info to named.conf
to pass the queries through an upstream server that does have full
internet access.

Running 'tcpdump port 53' in another window can help you see where
your query is going and whether you are getting answers.
