Zend Framework Quickstart Problem

I am not sure if I am the only person in this world who could not make the Quickstart run! But I am having problems setting things up. Every time I do this, I get an error:

-bash-3.00$ zf show version

Fatal error: Call to undefined method SplFileInfo::getRealPath() in 
/usr/local/lib/php/Zend/Tool/Framework/Loader/IncludePathLoader/
RecursiveFilterIterator.php on line 57

I have PHP running using version:

PHP Version 5.2.1

SPL from phpinfo():

...Rest of the Zend Framework files here...

I will update this post once I get things working. I am not sure if it is the current setup of my machine or I just missed something. I will continue to re-read and re-read the manual until I get frustrated. For now, off to a meeting…

Comments and suggestions below please

UPDATE:
I got a reply from the Nabble thread that I need at least:
PHP 5.2.2 ( SplFileInfo::getRealPath )
