Hey Dejan,

I'm running boxturtle
I already checked with roswtf and it doesn't complain:

1413 ros % roswtf

2010-05-07 20:52:02 flixr pts/2
Loaded plugin tf.tfwtf
Stack: ros
================================================================================
Static checks summary:

No errors or warnings
================================================================================

ROS Master does not appear to be running.
Online graph checks will not be run.
ROS_MASTER_URI is [http://localhost:11311]

cheers, Felix
