> version_builder.py uses the new xpath syntax only supported by ElementTree in Python
2.7 and newer. So running the example.py to invoke version_builder.py to create version XML
fails with the following error when Python  is version 2.6.x
> [root@myserver version-builder]$ python example.py
> Traceback (most recent call last):
>   File "example.py", line 38, in <module>
>     main(sys.argv)
