Hi,

I am trying to get the tf2 ROS package to run on Raspberry Pi under 
raspbian. I found slightly different instructions for that on ROS pages, 
probably due to different TF / TF2 versions. E.g. I tried following 
http://wiki.ros.org/tf2/Tutorials/Introduction%20to%20tf2 but I'm getting 
errors like

$ rosrun tf2_tools view_frames.py
[rospack] Error: package 'tf2_tools' not found

On the other hand 
http://library.isr.ist.utl.pt/docs/roswiki/tf2(2f)Tutorials(2f)Writing(20)a(20)tf2(20)broadcaster(2028)Python(29).html 
suggests to run

$ rosrun tf2 tf2_echo /world /turtle1

and that returns

[rosrun] Couldn't find executable named tf2_echo below /usr/share/tf2

I have the tf2-tools debian package installed, as is also apparent from 
the latter error message. Any ideas?

Thanks
Guennadi
