[vtkusers] Python + VTK:[vtkRenderWidget.py, vtkTkRenderWidget.py] core dump

[Dean N. Williams]

Prabhu,

    I will rebuild the VTK again and hope that this clears things up. 
Here is the
    outcome of running ldd on both shared libraries:

cloud% ldd  /data/vtk4.0/VTK/bin/libvtkRenderingPythonTkWidgets.so
        libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40144000)
        libdl.so.2 => /lib/libdl.so.2 (0x40159000)
        libGL.so.1 => /usr/X11R6/lib/libGL.so.1 (0x4015c000)
        libvtkCommon.so => /data/vtk4.0/VTK/bin/libvtkCommon.so (0x401c8000)
        libvtkFiltering.so => /data/vtk4.0/VTK/bin/libvtkFiltering.so 
(0x40399000)
        libvtkImaging.so => /data/vtk4.0/VTK/bin/libvtkImaging.so 
(0x403fe000)
        libvtkGraphics.so => /data/vtk4.0/VTK/bin/libvtkGraphics.so 
(0x406ca000)        libvtkRendering.so => 
/data/vtk4.0/VTK/bin/libvtkRendering.so (0x40964000)
        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40b4e000)
        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40b9a000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40ba2000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40bb9000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40c8e000)
        libm.so.6 => /lib/i686/libm.so.6 (0x40c9c000)
        libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 
(0x40cbe000)
        libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

cloud% ldd /data/ASD_work/cdat/lib/python2.2/lib-dynload/_tkinter.so
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40145000)
        libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
        libdl.so.2 => /lib/libdl.so.2 (0x4021b000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

Neither show the use of tcl/tk.
