setup.py breaks Modules/Setup.local

[Mike Romberg]

  I am attempting to get Modules/Setup.local working to build python
2.2.1.  But there seems to be a bad interaction with setup.py.  I have
a Modules/Setup.local which contains a definition for the _tkinter
module.  I would like to use a Tcl/Tk release from a location that
setup.py does not find.  It looks like this:

# Edit this file for local setup changes
*shared*

_tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \
        -L/usr/local/tcltk-8.3.2/lib \
        -I/usr/local/tcltk-8.3.2/include \
        -I/usr/X11R6/include \
        -ltk8.3 -ltcl8.3 \
        -L/usr/X11R6/lib \
        -lX11

# We don't want ssl sockets 'cause this opens
# up a whole can of DLL heck (often missing on stock redhat setups).
_socket socketmodule.c

*static*

  Now when I build python I see this:

  1.  _tkinter.o is built with the -I switches I want (this is good)

  2.  _tkinter.so is linked with the -L switches I want (also good)

  3. setup.py runs and relinks _tkinter.so with the incorrect -L
     switches.  (not good)

  Is there some way to prevent this?  Or is there something that I'm
not doing correctly?
