ENH: Only run python summary tests with compatible versions

The summary tests python script requires features that are
only available in python 2.7 and greater.  If the python
version is insufficient, simply disable the summary tests.

This was identified on a nightly dashboard build zoot.icl.utk.edu
where the python version found is 2.4.
