(I can't post the patch in sourceforge since the SSL login seems to be
down in the last three hours)
Python 2.0 (dinamic modules)
Mod_Python 2.6.2 (dinamic module)
GCC 2.95.2
Apache 1.3.14 (dinamic modules)
SunOS5 (Solaris 2.x)
I send the email also to "mod_python" mailing list since I detect the
problem using this package. Other developers could see the very same
problem!.
Mod_python runs smoothly until I do a "import zlib", for example, in a
handler. In this case, the request is aborted with the following log:

<<<<<
That is, "zlibmodule.so" tries to link to a function called "main".
Doing a "nm object|grep main", I see the unresolved reference in
"zlibmodule.so", but not in "zlibmodule.o". So, the problem seems to be
the creation of the shared library.
I tracked down the problem to the "configure" script: "cc -G" is (I
think) the right thing to do to create a shared library if you are using
the Sun compiler, but if you are using GCC (like me), the right command
is "gcc -shared".
