We should be using sys.hexversion which appeared way back in python 1.5

No, this is from PEP3109. http://www.python.org/dev/peps/pep-3109/

• raise Error, "Python-2.3 or newer is required"
• raise Error("Python-2.3 or newer is required")

There are more lines we should modify to adapt to python 3.

Andy has put this fix in 1.2.3 beta 1, and it's also now in trunk.
