Here is a port of py-dnslib which is used by some other ports I will shortly be submitting.
>From pkg/DESCR: A library to encode/decode DNS wire-format packets supporting both Python 2.7 and Python 3.2+. Comments or recommendations gratefully accepted as this is my first python library port. As I am not a committer, I will need someone to commit the changes on my behalf if approved. Thanks, Bryan
