Yes I did ./pybombs remove, which uninstalls everything. I also have pybombs set to install everything from source, so I know for sure what's being installed. All but PyQWT, because that source install is broken for some reason.
So the process is, I begin with
./pybombs install gnuradio
This installs all dependencies for gnuradio until it gets to PyQWT and fails. I then install PyQWT through yum, because that works. Then I restart the pybombs install the same way as before. It recognizes PyQWT as being installed via rpm and continues until completion.
