Hi Greg,

pybombs is pretty safe. It will only install stuff that successfully builds, so the chance that you wreck your installation are small, even if you decide to install stuff into /usr/local. However, you can also instruct pybombs to only install into  /home/greg/prefix (or any other directory of your choice), which will leave your whole system untouched. You delete /home/greg/prefix, and everything pybombs did will be undone :)

You should indeed uninstall GNU Radio if you have already installed it, but you don't have to -- the prefix method will work, nevertheless.
Pybombs will only need root privileges to install missing libraries from the Ubuntu archives.
Warning: If you plan to use Ettus USRPs, please make sure you *don't* have Ubuntu's uhd*, libuhd* or uhd-host packages installed; these range from old to archaeologically interesting.

Best regards,

I have noticed the fine work with Pybombs and picked up a more hardware and thought to myself:
"Hey, now is time to bite the bullet is start using Pybombs"
I don't want that bullet to shoot me in the foot (sorry).
Question:  What is the safest method to switch to Pybombs for a working installation?
My thoughts were to
1. Remove what I can manually and start over
2. Tell Pybombs to install into the ubunto /user/local/blah dirs.
