error: xml2-config not found. Please check your libxml2 installation.

重装mysql+apache+php,configure php的时候得到错误信息

shell#./configure--with-mysql=/usr/lib/mysql--with-apxs2=/usr/local/apache/bin/apxs --prefix=/usr/local/php
configure: error: xml2-config not found. Please check your libxml2 installation.
错误原因，xml2-config这个文件没找到。
／＊原因可能出在我这次安装redhat，有很多东西没选上，所以出此问题。＊／
根据错误提示，安装libxml2。RHEL_5.2的安装光盘上提供了很多rpm包，我的是dvd光盘，位置在/media/RHEL_5.2 i386 DVD/Server，
cd /media/RHEL_5.2 i386 DVD/Server
ls *libxml*
