Serious bugginess on Raspberry Pi

I've seen this before but wasn't alert enough to figure out that it was 
important since it worked everywhere else.  It's a general problem, nothing 
specific to the Raspberry Pi.

The problem I've seen is that ntpd isn't listening on the local IPv6 address 
that ntpq is sending on.  It's some combination of what's in /etc/hosts and 
what ntpd is listening on.

Ah...  It's listening on :: rather than ::1
$ netstat -uln
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State

udp        0      0 127.0.0.1:123           0.0.0.0:*                         

udp        0      0 0.0.0.0:123             0.0.0.0:*                         

udp6       0      0 :::123                  :::*                              


The /etc/hosts I use (almost) everywhere doesn't have any IPv6 info so ntpq 
gets 127.0.0.1 when it asks for localhost.
