AttributeError: 'tuple' object has no attribute 'major'

sys.version_info changed between 2.6 and 2.7, see http://docs.python.org/2.6/library/sys.html#sys.version_info (2.6) and http://docs.python.org/2/library/sys.html#sys.version_info (2.7).

You should use sys.version_info[0] instead of sys.version_info.major in setup.py lines 86 and 102.
