Comment 2 Valdis Kletnieks 2008-02-06 18:52:28 UTC 
Another failure mode - leaving off -6 generates a *different* error msg:

% dig @2001:503:ba3e::2:30 . ns 
dig: couldn't get address for '2001:503:ba3e::2:30': address family not supported

Other things are using IPv6 just fine - ssh, smtp, firefox, and other stuff.
Comment 3 Adam Tkac 2008-02-11 17:12:58 UTC 
This problem is due recent glibc changes. Bind has to be rebuild with
-D_GNU_SOURCE. Fixed in bind-9.5.0-26.b2.fc9
