Well there is an alternative. ``lit`` is available as a stand-alone
application via pypi at [1]
so what we could do is upgrade lit in the SVN repo to only support
Python >= 2.7 and note somewhere in the docs that
to use the old lit that works with python 2.6 they can do

$ pip install lit==0.4.1
$ lit -vs test/

This may eventually break if lit changes too much in SVN.

There's a list here [2].
