Missed those patches , sorry :-( should have tried one patch for the lot of
them.

I've been advised before to upload diff -u patches to the bug tracker. It
might be that cvs has changed since I uploaded the patches or I hadn't
updated my cvs source in a couple of days.

This is referenced from vtkXRenderWindowTclInteractor. I built on  a windows
machine and didn't pick this up. I see "vtkTkInternals.h" used to included
tclInt.h but the function prototype is used instead now.  I'm guessing Mac's
will need
#ifdef VTK_USE_CARBON
#include "tkMacOSXInt.h"
#endif

In the vtk source tree its here:
/VTK/Utilities/TclTk/internals/tk8.4/tkIntDecls.h

If you're compiling your own extension, you'll have to add this to
VTKConfig.cmake.in:
SET(TCL_TK_STUBS "@TCL_TK_STUBS@")

I notice that the vtk.exe doesn't work for my build, but tclkit does
successfully load the vtk libraries.

Another caveat is that while all the tcl scripts can be wrapped into a
starpack, the vtk libraries should remain unwrapped- starpacks cant load
dependent libraries. You should "lappend auto_path /path/to/vtk/libs"
somewhere before "package require vtk"
