Cross posting to vtkusers list as that may be more appropriate:
Can you rebuild VTK with these two settings:
CMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=ON \
VTK_USE_RPATH=ON
Run ccmake on your vtk build directory and set those two cmake
variables. Configure and build. After the build completes, then run
"make install".
The default installation location is in /usr/local. I would change it
to /usr/local/vtk-5.2.
Next, Get rid of extra Python builds on your system. The only python
build should be in /System/Library/Frameworks.
Now try to build your project. If everything goes correctly you should
NOT need to mess with DYLD_LIBRARY_PATH. The reason why you are having
to set that variable is because, as you found out, the vtk libraries
do NOT have an "install_path" (same as rpath on linux) set in them.
Without that set to anything besides the library name the linker will
not be able to encode the correct path in anything else that depends
on the vtk libraries. Which is some of your problems.
Let us know if you can get this far.
