Ah, is this on Raspbian Jessie Lite, or Wheezy?
It might be related to: http://forums.pimoroni.com/t/raspbian-jessie-lite-error-running-flotilla-solved/1341
And fixable by:
sudo apt-get update
sudo apt-get install libboost-system1.55.0
Otherwise I need to get the Wheezy binary and auto-installer working.
