php 5.2 doesnt support mysql 4.1 - what??

Hiya

For some reason when i compiled php 5.2 with the following,

Code:

./configure --prefix=/usr --with-xml --with-mm --enable-bcmath --enable-calendar --with-curl --with-dom --with-dom-xslt --with-dom-exslt --with-swf=/usr/local/flash --enable-ftp --with-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr --with-xpm-dir=/usr/X11R6 --with-gettext --with-imap=/usr/local/imap-2004g --enable-mbstring --enable-mbstr-enc-trans --enable-mbregex --with-mcrypt --enable-memory-limit --with-mhash --enable-magic-quotes --with-mm --with-mysqli --with-mysql=/usr --with-openssl --enable-discard-path --with-pdflib --with-pear --with-pspell --enable-xslt --with-xslt-sablot --enable-sockets --enable-track-vars --enable-versioning --enable-wddx --with-xmlrpc --with-zip --with-zlib --with-tidy --with-tidy-dir=/usr/local/lib/ --with-freetype --with-freetype-dir=/usr/local/lib

Drupal turns round during installation and says:

I can't seem to find any extensions for php5.2 for mysql or anything too Shouldn't these be generated during the compile and make install process???

Attached is the php.ini file which i believe is sym linked to zends directory where the ini file is located

also you can see the pph info here: http://82.195.142.5/~nite/phpinfo.php

How can i fix this, what needs to be changed so it can work with mysql 4.1? Do i need to upgrade mysql to v 5??

Thanks in advance!
