Pybombs default behavior is to install everything under your own user
directory, so that no sudo privileges are required, and setup_env.sh
sets various environment variables to make this "work".

The Gnu Radio website has undergone some changes lately, and Pybombs
itself has been radically upgraded as well--so there are some
dangling documentation pointers.

The best thing to do since you have a "mixed" installation, and an
apparently-working Pybombs-based install is to use your package tools
to remove the installed-from-binary-packages stuff:

sudo apt-get purge gnuradio gnuradio*
sudo apt-get purge uhd uhd* libuhd*
