Upgrading on RH ES3

I've got a server with RedHat ES3 running. It has PHP 4.3.2 installed but for an application I want to install I need a min of 4.3.9. This server also runs apache2.0. I can't find RPMs for RH ES3 so I downloaded the source for PHP4.4.1 figuring I would just compile myself. Problem is, the INSTALL file gives instructions based on the idea that you don't already have Apache2 or an earlier ver of PHP Installed already. Since Apache2 was installed via RPM originally the INSTALL instruction for PHP with Apache2 prob won't work. ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql It's the: --with-apxs2=/usr/local/apache2/bin/apxs Switch that has got me scratching my head. /usr/local/apache2/ doesn't exist and I can't find apxs anywhere on the sys. Can I just configure with ./configure --with-mysql?? Thanks, Jeff
