dba module not enabled

Hey php guys, Ok so I'm trying to compile php 5.6.6 with the --enable-dba=shared flag in order to enable the dba module. However when I grep the output of php -m or take a look at the output of phpinfo(); I don't see that the dba module is enabled. Here are my full configure flags: ./configure --with-apxs2=/opt/apache2/bin/apxs --with-zlib=/usr --prefix=/opt/php-5.6.6 --with-libdir=lib64 --with-config-file-path=/etc --libexecdir=/usr/libexec --with-bz2 --with-curl --with-gd --with-freetype-dir=/usr --with-png-dir=/usr/lib64 --enable-gd-native-ttf --with-iconv --with-jpeg-dir=/usr/lib64 --with-zlib --enable-exif --enable-ftp --enable-sockets --enable-sysvsem --enable-sysvshm --enable-sysvmsg --enable-wddx --with-kerberos --enable-shmop --enable-calendar --with-xmlrpc --enable-soap --disable-pdo --with-openssl --with-xsl -enable-dbx --enable-mbstring --with-mcrypt=/usr --enable-zip --enable-bcmath --enable-pdo --with-pdo-mysql=/usr --with-mysql --with-mysqli=/usr/bin/mysql_config --enable-zip --enable-dba=shared --with-gettext=shared --with-gmp --enable-ftp --with-pspell --with-config-file-scan-dir=/etc/php.d && make && sudo make install Any ideas at all on how I can correct this problem?
