 This is a bit convoluted, but please bear with me.  First of all, vtk5+x11
 (using macports x11 libs) produces a bus error for me on Tiger when I try
 to run any VTK program (c++ compiled or wrapped script).  I think this is
 due to mixed use of macports x11 libraries with apple opengl.  It works OK
 if I use apple X11, but I have not figured out how to force that using
 macports.

 Next I tried using cocoa rendering (-x11).  However,, the tcl wrapping of
 vtk using cocoa does not support all features, most notably interaction.
 Please see:

 The solution is to use x11 for both tcl/tk and vtk, but as noted above
 this fails on Tiger.

 Luckily, python and cocoa rendering seem to work fine together.

 Suggestions/requests:
  1. I have provided a patch to the portfile that provides a tcl variant.
 Since tcl does not fully work without x11, I think this is useful.
  2. Perhaps the x11 variant should be forced, or at least recommended, if
 the tcl variant is selected.
  3. I would appreciate any help getting x11 rendering to work on Tiger.
