Compiling new modules in PHP - required to remove old installation?

I currently follow the following steps when I need to compile a new module in PHP: 1) Delete old source folders for APACHE and PHP (/usr/local/src) 2) Stop APACHE service 3) Delete the installation directories (/usr/local/apache /usr/local/php4) 4) Re-configure APACHE 5) Re-configure PHP; make; make install 6) APACHE make and make install 7) Copy the original httpd.conf file to the installation directory (/usr/local/apache/conf/) 8) Start apache Then all works fine. If I leave out any of the above steps, the re-compilation doesnt work. Is there an easier way or do I need to do this each time? (process takes about 30mins each time) Running RH9 Thanks
