You can fix that by adding the missing headers to
visualization/nviz/src/

example for 8.4.9:

ls *8.4.9*
tkInt8.4.9.h  tkIntDecls8.4.9.h

The togl.c contains a set of 'if' + 'elif' to reflect the various
version numbers,
so update that, too. It's pretty straightforward...

Step-by-step:

1. download TK from http://tcl.sourceforge.net
    -> File Distributions
       -> View All Project Files
           -> tk8.4.9-src.tar.gz (example)

   extract:
    tar xvfz tk8.4.9-src.tar.gz tk8.4.9/generic/tkInt.h
    tar xvfz tk8.4.9-src.tar.gz tk8.4.9/generic/tkIntDecls.h

   and add here (rename!)
     tkInt.h      -> tkInt8.x[.y].h (e.g. tkInt8.4.9.h)
     tkIntDecls.h -> tkIntDecls8.x[.y].h (e.g. tkIntDecls8.4.9.h)

2. change within tkInt8.x[.y].h the include statement from tkIntDecls.h
   to tkIntDecls8.x[.y].h

3. edit togl.c
   add 'elif' statement with new names according to version
   of TK

4. complain about these stupid things to Tcl/Tk developers

(cited from README therein).
