Need an OrderedDict implementation for Python 2.6 about botocore HOT 2 CLOSED

odict works pretty well for me.

We want to use OrderedDict to preserve the order of the keys in the JSON
files but 2.6 doesn't have it in stdlib. Need to workaround that and also
then use simplejson on 2.6 to use the object_pairs_hook which json in 2.6
does not support.

Man, I was really hoping to do this without conditional install_requires but I'm not seeing a good way to do this.

I was planning on just vendoring Hettinger's OrderedDict backport into botocore and adding simplejson to the required packages to install because it works with python2 and python3. However simplejson doesn't work with python3.2 so this isn't really an option. I'm guessing we can just do a conditional install_requires for ordereddict and simplejson for python2.6? We might also want to include simplejson for python2.7 as well because it's much faster than the stdlib json module:

$ python --version
Python 2.7.3
$ python -m timeit -s 'import json' 'json.load(open("data/aws/ec2.json"))'
10 loops, best of 3: 22.3 msec per loop
$ python -m timeit -s 'import simplejson' 'simplejson.load(open("data/aws/ec2.json"))'
100 loops, best of 3: 8.46 msec per loop

You guys have any other suggestions? Otherwise I'll update install_requires. We'll also need to work something out for the requirements.txt file as well.
