Can't run in GNURadio. What version of usrp firmware are you using?

This error has nothing to do with UHD and the USRP. You obviously didn't install the module correctly. Make sure you have SWIG installed when compiling the OOT so that the bindings are generated.

This is no bug, so I'm closing the issue.
