An issue with installing praw in Ubuntu via pip

[SynedraAcus]

For me (Ubuntu 14.04LTS, python 2.6.7) sudo pip install praw or installing it with requirements.txt does not work. Using sudo python -m pip install praw works just fine. Sure, it's not an issue with your script, but if other users experience it as well, it'd be better to use python -m pip method in README.md. Complete log below.
