What timing!  I just finished digging down through wget and glibc
source to discover the problem myself.  Armed with knowing that I
found:

https://bugs.launchpad.net/ubuntu/jaunty/+source/glibc/+bug/313218

Which pretty much details my problems.  Seems Ubuntu just patched
glibc for their own distro and that's that.

glibc-2.10.1, actually.  :)

Yes, I will have to look into setting up such a proxy.  Any
suggestions on public DNS servers that handle this correctly?  I tried
Google's 8.8.8.8 and 8.8.4.4 but they seemed to ignore AAAA like
Qwest's servers do.
