Installs simplejson even though not needed.

[visteya]

My machine has Python 2.7.
I installed stallion with pip.
It installed simplejson, even though Python 2.6 and 2.7 have json in the standard library.
It appears stallion doesn't even import json, but uses json indirectly via flask jsonify.
You should consider fixing the dependencies to not install simplejson unless Python 2.5 is detected.
