rosvirtual machine for ardrone_brown package : rosrun problems

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Installation of Ros Virtual Machine
2. launching of "./build_sdk.sh"
3. lauching of "rosmake ardrone_brown"
4. launching of "rosrun ardrone_brown ardrone_driver"

What is the expected output? What do you see instead?
That should launch the achievable of the ardrone_brown package. But I obtain 
that:
[rospack] opendir error [No such file or directory] while crawling 
/home/brownrobot/ros/experimental/pr2-remote-lab
[rospack] opendir error [No such file or directory] while crawling 
/home/brownrobot/ros/stacks/tutorials

What version of the product are you using? On what operating system?
Ubuntu

Please provide any additional information below.
At the beginning, rosmake did'nt work so I modify some access paths in the 
Makefile of the package:
I change "home/aka1/pkgs/ardrone_brown" in 
"home/brownrobot/ros/experimental/ardrone_brown". But "rosrun" still don't work.

Few  additional information:
Now, when I launch "rosrun ardrone_brown ardrone_driver" I obtain that:
