Tom,

At the first run without 'readline', everything was OK except for one
error message:

.
.
touch add2lib
if test -f hassignal; \
        then echo removing sigcheck.o intrcheck.o; \
             ar d ../libpython1.5.a sigcheck.o intrcheck.o 2>/dev/null; \
        else echo leaving sigcheck.o intrcheck.o in; fi
removing sigcheck.o intrcheck.o
*** Error code 2 (ignored)
.
.

However python executable was built and working.

Then I wanted to install python-1.5.2 with readline 4.0. I first installed
readline, then modified /Modules/Setup.in, using the *.h and libreadline.a
from readline 4.0 (readline.c is the one with the python distribution).
The compilation of readline.c was OK, but I got the message I mentioned
in the previous post. 'make clobber' and 'make distclean; ./configure ...;
make' will solve that problem, but introduce another problem associated
with readline. 

Have you installed readline with your python? It seems that a function
'initreadline' which is required by /Modules/config.c is not inside the
readline package.

Thanks!
