You are right that I compiled my version of 4.2.4 with debugging and IPv6
disabled, and I also built my streamlined kernel without IPv6 support.

However, what you see above was actually the debug output from 
starting the stock ntpd 4.2.0 from a GENERIC kernel, which does enable 
IPv6. I would therefore expect the daemon to attempt to use IPv6 on 
startup.
