error launching world file in gazebo

edit

I was following this tutorial, but as i enter: roslaunch my_robot_gazebo my_robot.launch, i cant see the world in gazebo. When i enter: env | grep GAZEBO_RESOURCE_PATH, i cant see the gazebo in that path, when i checked my gazebo-2.2 was inside usr/share/local instead of /usr/local/share. I am using ros indigo. Befor this i have installed gazebo4 and than again uninstalled it as i knew ros indigo already provides gazebo2.2. Now i am this type of errors, what should i do? I am using ros indigo, ubuntu 14.04. I get this kind of error:

Error [Plugin.hh:149] Failed to load plugin libbaxter_gazebo_ros_control.so: libbaxter_gazebo_ros_control.so: cannot open shared object file: No such file or directory

What i see is when ever i run: rosrun gazebo_ros spawn_model -filerospack find baxter_description/urdf/baxter.urdf -urdf -z 1 -model baxter, the gazebo stops running.
