[Rock-dev] roby shell

[Allan E. Conquest]

Hi,

i have a new bootstrapped system with NEXT flavor. If I run MARS by
supervision and try to connect with the shell (both on my local
machine), I get this error message:

Then, I tried using tools/roby on master by editing
autoproj/overrides.yml followed by update and build. Now, I get a
different error message:

I also tried to use tools/* on master before with the same result. Any
ideas?
