[Therion] usr/bin/ld: cannot find -lvtkjpeg

Hi all I have downloaded therion-0.5 and the compile fails with: /usr/bin/ld: cannot find -lvtkjpeg Searching on google brings up some references but nothing that seems right for my problem. Im compiling on an Dell Intel machine with Debian. I have installed: libvtk5 and libvtk5-dev The dev package contains the file: /usr/include/vtk-5.0/vtk_jpeg.h I have modified the Makefile for loch to find the VTK directory: #VTKPATH = /usr/local/include/vtk-5.0 #VTKLIBPATH = /usr/local/lib/vtk-5.0 VTKPATH = /usr/include/vtk-5.0 VTKLIBPATH = /usr/lib/vtk-5.0 otherwise it couldnt fin the VTK include directory. How do I get this vtkjpeg ? Mike Lake
