GNURadio Fuckery

Stuff i discoverd while installing or using GNURadio:

1. Check before what Release you use
   I tried to use 3.7.13 without checking, installation failed.
   See if there is a patch available that is easy to implement. Like for 3.7.11

2. Set revision via PyBOMB does NOT use Release tags!
   It however uses commit hashes, so that works at least.

3. Keep backups of your VM, if not try not to lose sanity.
   Backup regulary, e.g. after each successful step.

4. Test EVERYTHING, AFTER EACH STEP
   Shit WILL fuck
