For a project I'm working on I needed to not use the default way of installing but instead I manually installed all of the dependencies in: https://github.com/osrf/homebrew-simulation/blob/master/gazebo6.rb

I tried making and installing it by:

cmake -DENABLE_TESTS_COMPILATION:BOOL=False ../gazebo
make -j4 install

But this causes the following errors as a result of the make command:

../gazebo/physics/libgazebo_physics.so.6.1.0: undefined reference to `gazebo::sensors::SensorManager::~SensorManager()'
../gazebo/physics/libgazebo_physics.so.6.1.0: undefined reference to `gazebo::sensors::get_sensor(std::string const&)'

I'm pretty much new to linux and can't find why this linking goes wrong.
