py26 tests require ordereddict

Running the py26 tests can give:

Python 2.6 doesn't have a native OrderedDict implementation it needs the ordereddict library.

(I'm guessing gate nodes must have this installed.)

    have a native OrderedDict implementation.

This fix was released long ago. Further, we no longer support Python 2.6
