HI,

While running any application with rviz using a vcg file, I get the same
error i.e. File [rospack find package_name] does not exist. Below given is
the following output..

vros@ubuntu:~$ rosrun rviz rviz -d 'rospack find turtle_tf'
/rviz/turtle_rviz.vcg
[ INFO] 1279749063.222485000: Loading general config from
[/home/vros/.rviz/config]
[ INFO] 1279749063.222872000: Loading display config from
[/home/vros/.rviz/display_config]
[ERROR] 1279749064.042076000: File [rospack find turtle_tf] does not exist

What is the cause of this error?
