	Well, these arent executables.  They are libraries.  From my 3.1.2
install -

$ file /usr/lib/vtkTk*
/usr/lib/vtkTkImageViewerWidget: ELF 32-bit LSB shared object, Intel
80386, version 1, stripped
/usr/lib/vtkTkImageWindowWidget: ELF 32-bit LSB shared object, Intel
80386, version 1, stripped
/usr/lib/vtkTkRenderWidget:      ELF 32-bit LSB shared object, Intel
80386, version 1, stripped
$

	Tkinter calls Tk underneath.  It is possible that Tkinter doesnt
know where to find the above libraries.  If you are using bash try this

$ export VTK_TK_WIDGET_PATH=dir_where_you_have_installed_vtkTk*Widget
$ python your_vtk_app.py

	On other shells try something similar.  It works for vtk-3.1.2
dont know if it will for vtk-2.4.
