extract vtk-5.4.2.tar.gz in "~/VTK-5.4.2"

$ mkdir VTK-5.4.2-build
$ cd VTK-5.4.2-build/
$ cmake ../VTK-5.4.2

open up CMakeCache.txt in your editor, find the following lines and make sure they are changed to these settings:
	VTK_WRAP_PYTHON:BOOL=ON
	BUILD_SHARED_LIBS:BOOL=ON

$ cmake ../VTK-5.4.2

This time you'll probably get some error messages about TCL. In CMakeCache.txt make sure the following line is set:
	VTK_USE_TK:BOOL=OFF

$ cmake ../VTK-5.4.2
$ make
$ make install

$ export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib/vtk-5.4
$ cd ~/ARS/bin
$ python FallingBall.py
