Yes - you can saftely ignore these 'DeprecationWarning:' messages. It
means : "the functionality works now - but it won't with newer
versions".

Python changed considerably between python-2 and the new
python-3. Python-2.6 is supporsed to be a bridge that enables easier
transition to python-3.

We need to eventually get configure working with both python3 and python2
