As a rule, distribution specific packaging issues like this should be handl=
ed=20
on distribution specific channels, not here.  I got the email you sent me=20
earlier in the week, but have been swamped and didn't get a chance to reply=
=20
yet.  For wheezy-backports it needs to have an alternate dependency on=20
python3-ipaddr since python3.2 doesn't have the ipaddress module like=20
python3.3 and later do.

I hope to have time to fix it this week.
