Note to all users on Ubuntu 12.04, one of the dependencies is not available
(osrf-pycommon) through the debian package system. We are working to fix
this, but if you want to try out catkin_tools 0.4.0 before then, you can
still install it via pip or from source:

http://catkin-tools.readthedocs.org/en/latest/installing.html#installing-from-source

Additionally, if you encounter problems with the second beta, you can still
install the previous release (0.3.1) with pip:


*pip install -I catkin_tools==0.3.1*

Thanks for the great feedback we're already getting!
