Gazebo Spawn_model fails when issuing rosrun [closed]

edit

Ubuntu 12.10 Graphics Card: NVIDIA GeForce GT 640M Gazebo Version: 1.7.11

In Tutorial: http://www.ros.org/wiki/simulator_gaz...

After creating the urdf model as indicated and running the spawn command:

rosrun gazebo spawn_model -file `pwd`/object.urdf -urdf -z 1 -model my_object

I get an error message stating that liblapack3gf.so cannot be opened (it is installed in my system). Here is the whole message:
