I have a colo client with minera on an rpi - hey upgraded through the gui and bfgminer ceased running (no 'screen') - they stupidly had upgraded all 3 taking them all down !

Eventually found this thread and tried the forced git but still didnt start it.

I have now compiled it again with the build_miner scripts and its working - so something in the update broke the shared libraries .so.0

Don't know what version they upgraded from though, sorry.
