Issues Building mycroft_ros

[BellLabsEAT]

Hi,

I am having issues with the final step of the installation process for this ROS package,

I have no issues in my process until I get to the last step to build the mycroft-ros package within the catkin workspace

catkin_make --only-pkg-with-deps mycroft_ros

Here is the output where I start to see issues:
`####

Any idea of what the issue might be?

try and checkout 0.5.2 tag of catkin_virtualenv and build from that
