Bug#658616: wget is unable to use IPv4 addresses for IPv6-capable servers
I file this on Squeeze version as this bug has been present for a long time.
However, for some odd reason (maybe related to freebsd-utils update?) this
has begun breaking Debian GNU/kFreeBSD installs.
On a pure IPv4 network with no IPv6 routing, GNU wget obtains IPv6 address
from host, and since it's unusable it falls back to IPv4 one:
$ LANG=C wget http://ftp.nl.debian.org/ -O /dev/null

Buxybox wget, however, stops here and fails:
$ busybox wget http://ftp.nl.debian.org/ -O /dev/null
Connecting to ftp.nl.debian.org ([2001:610:1908:a000::149:21]:80)
wget: can't connect to remote host: No route to host
I'm unsure why this didn't break D-I before.
