undefined symbol in libphp5.so

I'm trying to install php5 on an existing apache 1.3 server under linux without recompiling and reinstalling apache. I'm trying to avoid installing any extra software in addition to php so I've been disableing lmany things. I seem to need to disable another feature, but I haven't been able to figure out which it is. (I'm not a c/c++ programmer but I have many years work in other languages so I can usually puzzle things out) till now). the error I'm getting is: Syntax error on line 206 of /var/lib/apache_1.3.20/conf/httpd.conf: Cannot load /var/lib/apache/libexec/libphp5.so into server: /var/lib/apache/libe xec/libphp5.so: undefined symbol: sqlite3SelectDelete my ./configure line is currently: php-5.1.2> sudo ./configure --with-config-file-path=/etc --without-pear --enable-shared=yes --with-gnu-ld --quiet --enable-so=shared --with-apxs=/var/lib/apache/bin/apxs --disable-libxml --disable-dom --disable-simplexml --disable-xml --disable-xmlreader --disable-xmlwriter --without-pdo-sqlite Thanks PS I have tried searching php.net site which allowed me to solve all the previous problems I've had. NOTE: ./configure has to be run as root it seems to create the directory to hold libphp5.so. usually I only have to run the make install as root at the very end.
