Hi John, looks like the the problem /might/ (not sure) be that something tries to access a different version of the python libraries than you use now – so, seeing that simple_ra doesn't come with any code that needs to be compiled itself, it does look like there might be a remnant of your 14.04-time GNU Radio installation *somewhere* on the system.
Soo, checking the usual suspects: did you also recompile gr-osmosdr after you rebuilt GNU Radio and UHD?
