problem installing tkinter

[Johan Boeckx]

Hi,

I am trying to install tkinter with python 2.1.3. (from source) I followed
the instructions and changed the /Modules/Setup file for the tkinter part.
The  problem seems to be the
# *** Always uncomment this; X11 libraries to link with:
        -lX11

Because I receive during the make the follwing error :
gcc  -Xlinker -export-dynamic -o python \
                Modules/python.o \




            libpython2.1.a -lpthread -ldl  -lutil -L/usr/lib -ltk8.4 -ltcl8.
4 -lX11  -lm
/usr/bin/ld: cannot find -lX11
collect2: ld returned 1 exit status
make: *** [python] Error 1


Somebody who can help me ?
Greetz,
Johan
