newbie: help please!

[Steve]

hello,

i have python 2.2.1 installed on my mandrake 8.1 system, which seems to 
work fine.

The problem is im trying to install Tk exstensions, i have downloaded both 
tcl8.3.4 and tk8.3.4 files and installed using the ./configure, make and 
then make install commands. I then when into the setup file in the 
Python-2.2.1/Modules directory where i understand i have to enable the 
tkinter extension module, by uncommenting the approritae lines.

Lastly i run 'make' at the top of my Python-2.2.1 directory but i get this 
error:

gcc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -I./Include 
-DHAVE_CONFIG_H   -DWITH_APPINIT -I/usr/local/include -I/usr/X11R6/bin -c 
./Modules/_tkinter.c -o Modules/_tkinter.o
In file included from ./Modules/_tkinter.c:49:
/usr/include/tk.h:83:29: X11/Xlib.h: No such file or directory

i have the Xlib.h in the Python-2.2.1/Include directory

the tkinter part of my setup file looks like this and everything was 
installed in the default places
