IPv6 broken with Apache 2.2.19

[Nick Rosier]

Since the upgrade from Apache 2.2.17 to 2.2.19 I'm unable to get IPv6
to work; I keep getting following error:

# grep Listen httpd.conf
Listen x.x.x.x:80
Listen [2001:x:x:x:x::1]:80

# apachectl -t
[Wed May 25 17:18:18 2011] [crit] (OS 1)Unknown host: alloc_listener:
failed to set up sockaddr for [2001:x:x:x:x::1]
Syntax error on line 41 of /usr/local/etc/apache22/httpd.conf:
Listen setup failed

Any ideas what I'm doing wrong?
