You can try this code at the beginning of your program:

import sys
  if sys.hexversion < 0x10502f0: # 1.5.2 final
    print 'Get a new version of Python!'
except AttributeError:
  print 'Get a new version of Python!'

Dunno when sys.hexversion showed up, hence the try clause.

With more recent versions, you could also play with sys.version_info.
