Install Apache-PHP 4 on Centos 5.5

I have a project to migrate a server to a new machine. Currently using Centos 4.6 with services like: php4, postgresql, mysql, etc.
Since version 5, Centos is not including php4 packet in their distribution. So i have 2 choice:

1. keeping the current OS version and update the kernel
2. use the latest OS version and install php4 manually

My friend suggest option #2. I tried that and well done!!

Here's the steps:

1. Download php-4.4.9 and apache-1.3.42
2. Install apache, this should be easy.
3. Install php, this is the main challenge. the detail is next..
4. i'd use these modules: mysql, pgsql, gd. Then i installs devel packet of each modules.
5. It looks like gd requires zlib, jpeg, and png.. si i installed those packets with the devel parts.
6. Then i configure php
7. ./configure --with-mysql --with-apxs=/opt/apache/bin/apxs --with-pgsql=/usr/lib/pgsql/ --with-gd --with-jpeg-dir --with-zlib-dir --with-png-dir
8. make
9. make install
10. set "LoadModule php4_module libexec/libphp4.so" on httpd.conf
11. start apache
12. Done
