[Zope] zlib.so problem installing Zope-2.7.3-0

[daroczy]

Dear all,

I have installed SUSE 9.1 then have upgraded to Python-2.3.4 . I have compiled 
it.
Then I have compiled Zope-2.7.3-0. As result it has appeared the following 
message

peter at linux:~/Documents/zope/Zope-2.7.3-0> ./configure --prefix=/opt/zope

Configuring Zope installation

Testing for an acceptable Python interpreter...

Python version 2.3.4 found at /usr/local/bin/python

The optimum Python version (2.3.4) was found at /usr/local/bin/python.


The Python interpreter you are using does not appear to have the 'zlib'
library module installed.  For Zope to be able to run, you must install a
Python interpreter which includes the zlib module, or install the zlib library
into your Python interpreter manually.  The file which represents the library
is named 'zlib.so' (UNIX) or 'zlib.dll' (Windows) and is typically located in
the 'lib-dynload' directory of your Python's library directory.  Some
Python packagers ship the zlib module as a separate installable binary. If you
are using a system-provided Python installation, you may want to look for
a 'python-zlib' package (or something like it) and install it to make the
Python zlib module available to Zope.

Run the configure script with the --ignore-zlib option to prevent this
warning with the understanding that Zope will not start properly until
you've installed the zlib module.

Well, I have compiled zlib-1.2.1 
./configure -s; make test
make install
*** zlib test OK ***

As I have recompiled Zope-2.7.3-0 I have received again the message you see 
above.
I checked the /usr/lib/python/lib-dynload directory. The zlib.so is there.
What have I made wrong?

Any help would be greatly appreciated.
Thanks.
