OpenCV linker errors in ROS Fuerte

edit

I am trying to compile and test our packages from tu-darmstadt-ros-pkg with the upcoming ROS Fuerte from the official package repositories with Ubuntu Oneiric (amd64). Whenever a package is built which depends indirectly from OpenCV, I got strange linker errors about undefined references for OpenCV functions.

In this case I am trying to compile the object_tracker package, which depends from image_geometry, which uses OpenCV. This is the output from make VERBOSE=1:
