[Discuss-gnuradio] clean uninstall of Gnuradio and Pybombs

[Rachel Michelson]

Hello all,
I am very new to gnuradio, so please excuse a basic question.
I managed to install pybombs and gnuradio on my Ubuntu platform in 
several attempts. Various permissions issues got in the way and I ended 
up with multiple copies of the software in different directories, some 
more complete than others. Is there a clean way to uninstall the 
software and start from scratch?
Is doing a recursive rm on these extra directories sufficient or is 
there more to removing the packages?
Where do people typically install, under /usr/local? If so, all 
subsequent uses of pybombs and gnuradio require sudo? If using pybombs, 
will the entire gnuradio package also be under the pybombs directory 
tree?

thank you in advance!
