Well, yes, the error was completely NFS related and had nothing to do
with NTP. Google'ing a little gives the source code for that error:

  printk("RPC: Can't bind to reserved port (%d).\n", -err);

As you can see, the "(13)" shown was actually the error number, not the
port it was trying to bind to.

I had myself a similar problem with NFS yesterday -- when I shut down
the NFS server, make would give me a message about input/output error
(yeah, it's not a good idea to pull the plug from the NFS server while
