I have the same problem here, on a Linux version 2.6.32-5-amd64 (Debian
2.6.32-41), using the ITK tarball stable release.

Moreover when I was seeking for the wrapper's install path (to set the
env path), I found that :
  $ ls /usr/local/lib/cmake/ITK-4.0/WrapITK/
  ;CACHE;INTERNAL;PATH;subpath where where most of WrapITK files will be
installed

(the thing being listed is a directory name)
Seems like there's a problem with the installation scripts.

Anyway, I renamed this directory to src and set my env path like that :
        
        export ITKWRAPPEDINSTALLED=/usr/local/lib/cmake/ITK-4.0/WrapITK/src/
        export LD_LIBRARY_PATH=$ITKWRAPPEDINSTALLED:$ITKWRAPPEDINSTALLED/WrapITK/lib:/usr/local/lib/vtk-5.8/
        export PYTHONPATH=$ITKWRAPPEDINSTALLED/WrapITK/lib/:$ITKWRAPPEDINSTALLED/WrapITK/Python/

Here is what the famous previous dir contains :
        $ ls /usr/local/lib/cmake/ITK-4.0/WrapITK/src/**
        /usr/local/lib/cmake/ITK-4.0/WrapITK/src/WrapITKConfig.cmake
        
        /usr/local/lib/cmake/ITK-4.0/WrapITK/src/Configuration:
        CMakeUtilityFunctions.cmake  Generators           Typedefs              WrapITKTypes.cmake
        ConfigureWrapping.cmake      TypedefMacros.cmake  WrapBasicTypes.cmake


And my complete python error:
        >>> import itk
        >>> ls
        Traceback (most recent call last):
          File "<stdin>", line 1, in <module>

          File "/usr/local/lib/ITK-4.0/Python/ITKCommonPython.py", line 26, in swig_import_helper

        ImportError: libitksys-4.0.so.1: cannot open shared object file: No such file or directory
        
Hope that someone will be able to help me.

Kind regards,
