Umm.  But I thought that Python2.0 is not binary compatible with
Python1.5.x?  So doesnt it matter as to which version of Python is
used to build VTK? 

The other thing is - why do people have trouble with VTK on RedHat
7.0?  Does it have anything to do with the Tcl/Tk version or is it
something else?

Okay - in which case cant a simple note be made on the site (or
atleast somewhere else) saying something like

   This version of the vtk nightlies for this OS requires you to have:

     (1) Python version >= x.y.z that is avlbl for dwnld "here".

     (2) Tcl/Tk version >= x.y.z that is avlbl for dwnld "here".

     and anything else worthy of mention.  Dont you think this will
     save a lot of hassle for new users of VTK?

I must have missed something but this is what I understand:

   (1) The current vtk nightly binaries for Windows will work properly
   if the user has

       (a) Either Python 1.5.2 or above (i.e. it will also work for
       Python 2.0)

       (b) Will work only with Tcl/Tk version 8.2.

   (2) The nightly RPMs will work with

      (a) Python >= 1.5.2 (including 2.0).

      (b) Tk version ??  I am not sure of this.

Is this correct?
