Solution:  put Tcl/bin into the PATH variable through the System
environment tab.  Made easier by reinstalling Python and Tcl outside
Program Files (avoiding the evil space-in-filename issue) which however
was not effective in itself.  Thanks to those who suggested augmenting

Still working on this one.  Reinstalling Python and Tcl outside Program
Files changes the error message:

    >>> import Tkinter
    >>> Tkinter._test()
    Traceback (innermost last):
      File "<stdin>", line 1, in ?
      File "D:\Python\Lib\lib-tk\Tkinter.py", line 1947, in _test
	root = Tk()
      File "D:\Python\Lib\lib-tk\Tkinter.py", line 886, in __init__
	self.tk = _tkinter.create(screenName, baseName, className)
    TclError: Can't find a usable tk.tcl in the following directories:
	. D:/Tcl/lib/tk8.0 ./tk8.0 ./lib/tk8.0 ./library ./tk8.0/library ./library D
    :/Tcl/tk8.0/library
    
    D:/Tcl/lib/tk8.0/tk.tcl: bad event type or keysym "MouseWheel"
    bad event type or keysym "MouseWheel"
	while executing
    "bind Listbox <MouseWheel> {
	%W yview scroll [expr - (%D / 120) * 4] units
    }"
	(file "D:/Tcl/lib/tk8.0/listbox.tcl" line 179)
	invoked from within
    "source [file join $tk_library listbox.tcl]"
	(file "D:/Tcl/lib/tk8.0/tk.tcl" line 151)
	invoked from within
    "source D:/Tcl/lib/tk8.0/tk.tcl"
	("uplevel" body line 1)
	invoked from within
    "uplevel #0 [list source $tkfile]"
    
    
    This probably means that Tk wasn't installed properly.

Note that tk.tcl is present, in D:/Tcl/lib/tk8.0, contrary to the error
message.  I've exercised some of the Tk demos directly and they seem
OK.  Suggestions?
