Subject: [PATCH] require msgpack >= 0.4.6 and < 0.6.0, forbid 0.5.0.

maybe this is the easiest way for us to deal with msgpack compatibility.

0.5.0 release had some troubles:
- FutureWarning on stderr disturbing other output there, breaking tests
- pip install -U broken due to a pip issue with the transisition pkg
  which was needed due to the package rename (ImportError for msgpack)
- some linux dists not packaging the transition pkg
