cgminer 4.9.1 on a raspberry pi2

Built from commit # 57de2cc.  The newer commits wouldn't build for me at the time (Mar 7).

BTCdig seems to be claiming my hashrate is a little low; slightly in range for this lottery.  currently 207 hourly.  I started mining about 2 minutes before the official start of the contest, so it doesn't leave much room for mining to be down for any reason (internet going down, cat pulling on a usb cable, etc)
