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')

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sufficient, if mildly out of date.
