Stem no longer supports python versions less than 2.7
Since the addition of OrderedDict usage 2 months ago https://gitweb.torproject.org/stem.git/commitdiff/d30a628e5da06699d8533f92c4b1c496510213b8
the library no longer supports versions of python less that 2.7 ! The OrderedDict was only added in python 2.7
There are several solutions I guess :)
- decide to only support 2.7 ?
- implement an alternative OrderedDict e.g. http://code.activestate.com/recipes/576693/
- stop using the OrderedDict ?
