Newbie: compiled with --with-dbx but dbx_connect is undefined

I'm new to PHP and installed as follows (not for production use with Apache 2): PHP 5.0.2 and Apache 2.0.50 on Suse 9.1. When I try to use dbx_connect(), I get this: Fatal error: Call to undefined function dbx_connect() in /www2/htdocs/test1.php on line 9 phpinfo() shows that it was configured --with-dbx: './configure' '--with-mysql' '--with-pgsql' '--with-sqlite' '--with-apxs2=/www2/bin/apxs' '--with-gd' '--with-openssl' '--with-zlib' '--with-readline' '--with-dbx' ... but there is no DBX section in the phpinfo() output. In the "make install" output, I saw this: libtool: install: warning: remember to run `libtool --finish /home/scott/Download/php-5.0.2/libs' When I ran it, it said this: Libraries have been installed in: /home/scott/Download/php-5.0.2/libs I know the libraries should be installed someplace a little more public than my Download subdirectory. I don't know if this is related to the above problem or not. Any help would be greatly appreciated! Scott
