This could very well be my fault. I told you to set LD_LIBRARY_PATH like this:

  export LD_LIBRARY_PATH=${INSTALL_PATH}/lib/vtk-5.4:${LD_LIBRARY_PATH}

But that would be for VTK 5.4, not 5.6, which is installed by Dorsal.
Try this instead and see if it fixes the problem:

  export LD_LIBRARY_PATH=${INSTALL_PATH}/lib/vtk-5.6:${LD_LIBRARY_PATH}
