Conflict with pip library "jsonrpc" breaks requirements replication

[omigeon]

(I open a new issue since I don't know if the pip library is the same as "python-json-rpc").

Virtualenv A :

pip install jsonrpc
# this will overwrite the previous one in site-packages/jsonrpc, 
# but won't delete the egg.info directory
pip install django-json-rpc 
# For exampe, "from jsonrpc import jsonrpc_method" works
pip freeze > requirements.txt
# Since pip freeze lists packages in alphabetical order, we have django-json-rpc before jsonrpc
# Let's copy requirements.txt ojn machine B to replicate our virtualenv

Virtualenv B :

pip install -r requirements.txt
# install will follow the alphabetical order and jsonrpc will overwrite django-json-rpc
# "from jsonrpc import jsonrpc_method" won't work.

So we apply the same requirements.txt file to two virtualenvs end we end up with two differents librairies...
Your package should really install itself in site-packages/django_jsonrpc or something.
