Error during Pip install on Ubuntu 16.04

[Michael O'Brien]

Used http://airbnb.io/superset/installation.html as the basis for installing

While Python3 is available on Ubuntu 16 its not the default so carried on install using python 2

Created a virtual environment called Superset to hold the python packages and ran pip install superset but I get permission denied about billiard.so
The output is given below but there were no other errors which took place on a clean Ubuntu 16.04 vm with latest updates installed. I also updated pip and setup tools as per the installation guide above

Any pointers how to fix it?

My mistake I forgot to activate the virtual using source [virtualenvironname]/bin/activate before running the pip command
