PYTHON and PHP Errors

I have observed the following messages in my apache2 error_log on Fedora 3
after an update:

I have found the php libs in the /usr/lib/php4 dir.
rpm -qa php produces:

php-mysql-4.3.10-3.2
php-pear-4.3.10-3.2
php-4.3.10-3.2

rpm -qa python produces:

gnome-python2-canvas-2.6.0-3
libxml2-python-2.6.16-3
rpm-python-4.3.2-21
dbus-python-0.22-10.FC3.2
python-2.3.4-13.1
gnome-python2-gtkhtml2-2.6.0-3
gnome-python2-bonobo-2.6.0-3
gnome-python2-2.6.0-3

I do not know why the php libs imap.so and libldap.so or mod_python libs are
no longer compatible with apache2. I have not knowingly made changes to the
apache2 conf file or modules.

While searching for answers, I ran across a discussion where a solution
offered for php4 was to install libapache2-mod-php4. In search for
libapache2-mod-php4, I found only debian instructions.

So, before I enter into RPM hell or worse, I thought I better ask if someone
knows an easy solution first.

What should I do to troubleshoot this problem?

Thanks
