This is an issue with a missing symbol in the UHD driver (for USRP
hardware). Do you have the USD packages installed? (check with 'dpkg
-l | grep uhd')

uninstall all of the gnuradio stuff and re-install? AFAIK, it was all
done using the Ubuntu package manager. PyBOMBS is not installed on
this machine (yet).

I generally find the Ubuntu packages are up to date enough for
everything I want to do. I do, however, build my own libhackrf, but
that's mostly because I'm working on it. If you're not likely to
modify the GNU Radio code or HackRF code, then installing from the
Ubuntu repositories should be sufficient, if mildly out of date.
