Togl cannot be loaded

[SC Zhong]

Dear all,

I have an application which use the togl extension
of Tk through python.  I tried to compile python
again with the activation of the togl extension
in the Modules/Setup file.  But somehow the togl
cannot be loaded:

>>> from Tkinter import * 
>>> mst = Tk() 
>>> mst.tk.call('package','require', 'Togl') 
Traceback (innermost last): 
  File "<stdin>", line 1, in ?  
TclError: can't find package Togl
>>> 

There are no compiling errors.  I also searched a lot but
couldn't find some useful documentation of this 'module'.
I have python1.5.2 and on SGI.  The relevant part of the Setup file is: 

# *** Always uncomment this (leave the leading underscore in!):
 _tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \
# *** Uncomment and edit to reflect where your Tcl/Tk headers are:
