Subject: TCPServer only binding to INET6 interfaces?

Under FreeBSD 5.0-RELEASE running ruby 1.6.8, the following code:

----
require 'socket'

server = TCPServer.new(9999)
client = server.accept
----

only seems to bind to port 9999 on ipv6 interfaces.

% netstat -an | grep 9999
tcp6       0      0  *.9999                 *.*                    LISTEN
%

It works, however, when I specify a host to bind to.  It only fails when 
trying to use INADDR_ANY..

I cannot tell for sure whether this is due to changes in FreeBSD, ruby, or 
a combination of both.  However, my guess would be ruby since I have many 
daemons binding to INADDR_ANY and running fine.  Is anyone else running BSD 
(or perhaps other OS') with IPv6 support still in the kernel able to 
duplicate this problem?

Thanks in advance,
