Description of problem:
wu-ftpd won't startup in standalone mode.  It logs a "Cannot create socket to
listen on: Address family not supported by protocol" error in /var/log/messages
and quites.  This sounds like the same problem as in bug 64764, but it's still
happening in Red Hat 8.0. I've run netstat -apt as I suggested to the other
person to ensure that xinetd was no longer holding the socket and it isn't. 
I've tried starting it 20 minutes after disabled wu-ftpd in xinetd to see if
that helped and it didn't.  Interestingly the same error message is given even
if xinetd has the socket:

[root@ahps xinetd.d]# netstat -apt | head -2
