Hi,
I am trying this tutorial on Boxturtle installed using deb packages on
Debian Squeeze. I am having few errors:

 nitin@tangri:/tmp/ros_tutorial/awesomeros$ roslaunch awesomeros
robot.launch 
... logging to
/home/nitin/.ros/log/8897cb0a-8bfc-11df-ac0c-00248119e15c/roslaunch-tangri-26243.log

ROS_PACKAGE_PATH[/opt/ros/boxturtle/stacks:/tmp/ros_tutorial]

It is reporting non-availability of pkg test2. I just updated move_base.xml 
to path of required files. On launching again, navfn_yaml is not found. Here
is the output:

nitin@tangri:/tmp/ros_tutorial/awesomeros$ roslaunch awesomeros robot.launch 
... logging to
/home/nitin/.ros/log/8897cb0a-8bfc-11df-ac0c-00248119e15c/roslaunch-tangri-26262.log

error loading <rosparam> tag: 
	file does not exist [navfn_params.yaml]
XML is <rosparam command="load" file="navfn_params.yaml"/>

Am I missing something?

Also about running this tutorial on Cturtle (installed for deb), has anyone
updated world file for stage. I do not have knowledge about stage. I had
tried augmenting pose values with extra argument is not helping. Result is a
blank window!

Thanks
nitin
