ERROR: cannot launch node of type [msf_updates/pose_sensor]: can't locate node [pose_sensor] in package [msf_updates]

[ghost]

I am following the tutorial and have compiled the package in the catkin workspace. I tried to get the new namespace and launch the filter but I am unable to do so because I get an error that the pose_sensor node cannot be located. I have source'd my devel/setup.bash. However, that hasn't fixed the problem. What else I can try to do? When I try to run rosrun rqt_reconfigure rqt_reconfigure, my dynamic reconfigure is empty.

Anybody have any idea what is going wrong?
