Installing PHP on AMD64

Hi, I am trying to configure PHP 5.1.2 on an AMD64 server. When you try to configure php with links to /usr/lib64 is still looks in /usr/lib for the .so files. Is this a bug or is there special instruction to configure PHP on 64bit. I did get PHP to configure by using the --with-libdir=lib64 ./configure \ --with-libdir=lib64 \ --with-mysql=/usr/local/mysql \ --with-mysqli=/usr/local/mysql/bin/mysql_config \ --enable-soap \ --enable-calendar \ --enable-ftp \ --with-zlib-dir=/usr \ --with-gd \ --with-jpeg-dir=/usr \ --with-png-dir=/usr \ --with-tiff-dir=/usr \ --with-freetype-dir=/usr \ --enable-exif But I have to create a sys link for the mysql lib for the configure will find the lib files. ln -s /usr/local/mysql/lib /usr/local/mysql/lib64 Does anyone know that the right way to configure php on a b4bit system is???? My method worked but I don't think it is the right way. Thanks, Mark.
