Configuration Error

Hi, I am trying to get PHP installed to work as a module for Apache. I am very new to this process. Here is my problem Following the instructions at http://us2.php.net/manual/en/install.unix.apache.php Everything went well until I tried step 10: Now, configure your PHP. This is where you customize your PHP with various options, like which extensions will be enabled. Do a ./configure --help for a list of available options. In our example we'll do a simple configure with Apache 1 and MySQL support. Your path to apxs may differ from our example. ./configure --with-mysql --with-apxs=/www/bin/apxs The error I get is "Configuring extensions checking whether to enable LIBXML support... yes chechking libxlm2 install dir... no configure:error: xml2-config not found. Please check your libxml2 installation" My system is Red Hat 8. (I am also new to Linux). I checked and I have no xml2-config file on my drive.When I googled this error message I found nothing that made sense to me. Any help would be greatly appreciated. Andrew
