PHP and phpMyAdmin on Mac G5 with OS 10.5.6

The phpMyAdmin 3.1.5 documentation says that, if at all possible, I  
should
1. Download the latest versions of PHP and MySQL so that they will  
work with phpMyAdmin 3.1.5
2. Make sure I have the requirements listed below (see Requirements  
below)

I am a newbie with all this, and I am hoping someone can tell me:
    1.  Does PHP 5.2.9 (the latest stable version) include the  
requirements for phpMyAdmin 3.1.5 listed below?
    2.  If not, how do I enable, or obtain, these requirements?

  Requirements:

According to the phpMyAdmin 3.1.5 Documentation (http://demo.phpmyadmin.net/STABLE/Documentation.html#require 
) the following are required:

-- PHP 5.2.0 or newer, with session support and the Standard PHP  
Library (SPL) extension. 

-- PHP zip extension (to support uploading of ZIP files). 

-- mbstring and ctype extensions (for proper support of multibyte  
strings , eg. UTF-8, which is currently default). 

-- GD2 support in PHP to display inline thumbnails of JPEGs ("image/ 
jpeg: inline") with their original aspect ratio 

-- When using the "cookie" authentication method, the mcrypt extension  
is strongly suggested for most users and is required for 64–bit  
machines. Not using mcrypt will cause phpMyAdmin to load pages  
significantly slower. 

      FYI – The apple.com site listed these technical specifications  
for my machine:
      -- PowerPC processor architecture with 64-bit data paths and  
registers
      -- Native support for 32-bit application code
      Do these statements mean my machine is a 64-bit machine, and  
consequently requires the mcrypt extension?

-- When compiling php, we strongly recommend that you manually link  
the MySQL extension of your choice to a MySQL client library of at  
least the same minor version since the one that is bundled with some  
PHP distributions is rather old and might cause problems. 

How do I perform this manual link?

About My System:

I have a PowerMac G5 (PPC), OS 10.5.6 which has the following versions  
of PHP and Apache:
-- PHP 5.2.6 (Zend Engine 2.2.0) 
-- Apache 2.2.9 

PHP and Apache have NOT been enabled on my machine.

My Plan:

I'm planning to download the following:
-- 32-bit version of MySQL 5.1 for the PowerPC G5, OS 10.5
-- PHP 5.2.9
-- phpMyAdmin 3.1.5 

Thanks in advance for any advice you might have.
