Hi Prabhu,

I had the same problem, the widgets aren't broken, it's just a build
dependency problem.

Touch vtkTkRenderWidgetPython.cxx and rebuild, then your problem should
be gone.

Unfortunately vtkTkRenderWidgetPython.o is not re-built when
vtkTkRenderWidget.cxx is modified.  I don't know if there is any
way to enforce the dependency in CMake.
