[TYPO3] tx_yafi - Fatal Error

It looks like many people had this problem when trying to port their
scripts from PHP4 to PHP5. PHP offers some merging instructions and
tells the following:

Illegal use of string offsets causes E_ERROR instead of E_WARNING.
EX :
<?php
  $a = "foo";
  unset($a[0][1][2]);
?>
Fatal error: Cannot use string offset as an array in ... on line 1

So first of all i tried to install PHP4-CLI but script tells me that
at least PHP 5.2 is needed to run Typo3(?).
I'm looking into the PHP code now but I doubt that I will figure something out.
