The problem is specific to creating new Tk widgets; this requires the
"internal" headers, while other uses of Tk only require tk.h.

Basically, the Tk packages available from Linux distribution vendors
don't usually include the header files which are necessary for
creating new widgets.

The only options for NVIZ are to either:

1. Require a working Tk development environment, including TkInt.h
etc; this will typically require the user to build Tk from source.

2. Supply the missing files for all common versions of Tk.
