httpie is already available through pip :

pip install --upgrade pip setuptools
pip install --upgrade httpie

@thutex There are a lot of python packages in the repo that could be grabbed with pip. That's not the point. If it's a nice piece of software, it's much easier for people to find it when it has been included in the repo than if it just out in the wild. Plus, this also lets us optimize the build to make some things run faster or use native libs through dependencies.
