MySQL unavailable after compile and Install

Hello: On RHEL4 I build PHP 5.1.2 with the following configure command: ./configure --cache-file=../config.cache --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --libexecdir=/usr/libexec --datadir=/usr/share --sysconfdir=/etc --sharedstatedir=/usr/com --localstatedir=/var --libdir=/usr/lib --includedir=/usr/include --infodir=/usr/share/info --mandir=/usr/share/man --build=i386-redhat-linux --host=i386-redhat-linux --target=i386-redhat-linux-gnu --with-libdir=lib --with-apxs2 --disable-debug --with-layout=GNU --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-exec-dir=/usr/bin --enable-magic-quotes --disable-rpath --with-libxml-dir=/usr --with-openssl --with-pcre-regex=/usr --with-zlib --enable-bcmath=shared --enable-calendar --with-curl --enable-dom=shared --enable-exif --enable-ftp --with-gd=shared --with-jpeg-dir=/usr --with-png --with-png-dir=/usr --with-freetype-dir=/usr --enable-gd-native-ttf --with-gettext --with-gmp --with-imap-ssl --with-ldap=shared --enable-mbstring=shared --enable-mbregex --with-mime-magic=/usr/share/file/magic.mime --with-mysql=shared,/usr --with-mysqli=shared,/usr/bin/mysql_config --enable-shmop --enable-ucd-snmp-hack --enable-sockets --without-sqlite --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --with-xml --with-expat-dir=/usr --enable-xmlreader=shared --with-xmlrpc=shared --with-iconv --with-xsl=shared,/usr --with-pear=/usr/share/pear --enable-memory-limit --with-pic --with-dom-xslt=/usr --with-dom-exslt=/usr --enable-track-vars --enable-trans-sid --enable-yp --enable-mbstr-enc-trans Please note the --with-mysql and --with-mysqli switches. However, my phpinfo() output does not show either mysql or mysqli as avaialbe. Did I miss a step? I am pretty new at compiling and installing so the obvious may be the answer.
