The downside of this approach is that it makes all syntax errors
look like missing Python 2.0 features:(

Why not something similar:

====wrapper module
import sys
try:
   # sys.version_info is a python 2.x goodie
   sys.version_info[0]
except AttributeError:
   # you could extract and test from sys.version here like
   # if sys.version[0] == "1":
   print "This program requires Python 2.0"
   sys.exit(1)

import realProgram
