How to I fix libgazebo_ros_paths_plugin.so undefined symbol error?

edit

I recently upgraded to the most recent packages of ROS hydro and now when I launch gazebo using "rosrun gazebo_ros gazebo" I'm getting the following error:

gzserver: symbol lookup error: /opt/ros/hydro/lib/libgazebo_ros_paths_plugin.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2_RSt6vectorISsSaISsEE

gzclient: symbol lookup error: /opt/ros/hydro/lib/libgazebo_ros_paths_plugin.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2_RSt6vectorISsSaISsEE

Using c++filt or http://demangler.com/ , I see that the following method is undefined:

ros::package::getPlugins(std::string const&, std::string const&, std::vector<std::string, std::allocator<std::string=""> >&)

Does anyone know how to fix this?

Here are the ROS / Gazebo packages I have installed on my Ubuntu 12.04.4 64-bit computer:
