pyyaml fails when installing

[Peyton-Smith05]

Howdy,

I am currently trying to run python2 setup.py and I am getting an issue with the package dependency pyyaml. I am running on a virtual box Ubuntu 16.04.07. Below is the error output.

Step 43/55 : RUN pip install pyyaml

Sorry for the delay, but I should note LAVA is being fully re-modernized, hope to get this fully updated by August latest.
