add xsl support to php

["Gagan Bajpai" <gagan.bajpai@xxxxxxxxx>]

Hi,

I'm new to php and please let me know if I should post this question on some other list.I have already installed php5.2.2 on centos using rpms. 
By default when I run "php-m" the xsl.so is not installed. is there a way through which I could upgrade my php nstallation
to have xsl.so .
I already have libxslt.so installed and 'xsltproc' works fine. I just somehow want to ensure that xsl support is enabled.
Upon googling I found that I need to do a configure -with-xsl. But 
1. I never installaed php from source.
2. I don't want to reinstall php, just want to tell php(if I may use this language) that using existing libxslt for xsl support. 
In other words, if already have libxslt and php 5* installed how do I create right xsl.so.
