Looks like the dependencies are not all listed. I am running a mostly stock system here with no python installs besides what xfce4 and some tools want to have. When trying to run the networkmgr, it simply quits and does nothing. Now before I hit you with several hundred KB worth of ktrace output, I will see if something jumps out at me, but it is some reading I need to do.
But bashing/complaining without any (prior) initiation, isn't of any value to anyone.
sudo(8) is a pre-req, as root has no place on the desktop (Xorg(1). So all of the commands (if not already provided by the scripts) need to be prefaced by sudo(8). In a future version, I will add the option to make(1) for su(1), as well. But let's try to get this running smoothly, rather than adding additional variables, first.
