asctec@asctec-mastermind:~/fuerte_workspace/sandbox/beginner_tutorials$ roscore

This is the same problem as: http://answers.ros.org/question/20780...

They are different problem. In fact I have pip uninstall packages in /usr/local/lib/python2.7/dist-packages and you can see my rospkg is now in /usr/lib/python2.7/dist-packages.
