I have been searching for weeks too.

Then I used

Yum erase php*
Yum erase apache*

Downloaded Apache 2.0.54 source , ./configure, make and make install
Downloaded PHP 5.1.2 source .. and did the same
Adjusted the PHP.ini file

All works fine now.
Remember to set Major/Minor_Version
to
MODULE_MAGIC_NUMBER_MAJOR = 20020903; { Apache 2.0.51..54 }
MODULE_MAGIC_NUMBER_MINOR = 9;

and recompile some language modules, if you develop static modules or cgi's

> BACKGROUND:
>
> I have successfully reinstalled an Apache 2.x webserver under a
> freshly installed Linux (Fedora Core 4) operating system. All
> current operating system patches have been applied.
>
> Following firebird.org's documentation for a client-only install
> under Linux, I have copied libfbclient.so.1.5.1 from the server
> machine's /opt/firebire/lib directory into the /usr/lib directory of
> the client machine.

> I have also created chained symlinks using the following commands:

> ln -s /usr/lib/libfbclient.so.1.5.1 /usr/lib/libfbclient.so.1
> ln -s /usr/lib/libfbclient.so.1 /usr/lib/libfbclient.so
> ln -s /usr/lib/libfbclient.so /usr/lib/libgds.so.0
> ln -s /usr/lib/libfbclient.so /usr/lib/libgds.so
>
> The firebird.msg file from the server installation has been copied to
> the /opt/firebird directory on the client machine.
>
> The FIREBIRD environment variable has been created on the client
> machine and ponted to /opt/firebird.
>
> Apache 2.x and PHP 5.x have been successfully installed and tested. I
> need now to add the --with-interbase extension.
