Hey Marcus, and anyone else,  
I tried that clean and then remaking, and nothing changed. Any other  
suggestions?  
Thanks,

Uninstall the binary UHD that you installed and build UHD and GNU Radio  
from scratch using ‘./pybombs install uhd gnuradio’:

[http://gnuradio.org/redmine/projects/pybombs/wiki](http://gnuradio.org/redmine/projects/pybombs/wiki)

The error is possibly being caused by a UHD version mismatch.
