Red Hat 6.2 and PHP-4.0.5

I recently spent the better part of a day trying to get PHP to install and run properly on my system. I am using Red Hat 6.2 and have installed all of the apache RPMs and tried building PHP from source with ./configure --with-apxs=/usr/sbin/apxs and everything seems to be ok and i do a make and make install and check httpd.conf and restart apache. The problem is when I go to test and see if PHP is working, nothing happens. I created a test.php file and in it i have <?php phpinfo() ?> which when I point my browser at that file that's what I see, not the expected PHP info screen. I'm not sure what the problem is....I had this problem with my Red Hat 7.0 machine and after countless hours of trying to get it to work it just "out of the blue" decided to work. I'm pretty much at a loss, I can't see anything wrong. If anybody can help, I'd be grateful because I'm about the throw the box out my third story window. :) Thanks, Eric
