新人PHP 编译出错，知道的朋友帮忙解答一二。

操作系统为Opensuse 11.4 编译PHP提示错误如;configure: error: xml2-config not found. Please check your libxml2 installation.
在/usr/local目录中已经编译并成功安装了libxml2文件，为什么还提示config not found .
请问应该从何下手解决此问题，
在此先谢谢！

编译过程如下;
./configure --prefix=/usr/local/ --with-apxs2=/usr/local/httpd-2.2/bin/apxs --with-curl=/usr/local/curl --enable-ftp  --with-expat-dir=/usr/lib --enable-soap --with-gd=/usr/local/gd2/ --with-jpeg-dir=/usr/local/jpeg6/ --with-zlib-dir=/usr/local/lib/ --with-png=/usr/local/lib/ --with-freetype-dir=/usr/local/freetype/
