Basically, I've tried (many times) to install Apache 2.0.55 and PHP 5.1.1 from source, but to no avail. They both compile and install, but I cannot start Apache.

Here is the error message which I receive when I try to start apache (which is installed in /usr/local/apache:

# ./apachectl start

Syntax error on line 232 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: undefined symbol: add_assoc_stringl_ex


I've compiled PHP 5.1.1 as a module (as can be seen from the above). Here are my configure lines which I used:

Apache:
./configure --enable-ssl --enable-module=php5 --prefix=/usr/local/apache --enable-vhost-alias --enable-so --enable-rewrite --enable-speling --with-mpm=prefork      

PHP 5.1.1:
./configure --with-mysql --with-xml --with-openssl=/usr/local/ssl --with-apxs2=/usr/local/apache/bin/apxs --with-curl=../curl* --enable-shared-pdflib --with-gd=../gd-2.0.33 --with-jpeg-dir=/usr/lib --with-xpm-dir=/usr/lib --with-png-dir=/usr/lib --with-zlib-dir=/usr/lib      


Thank you for your assistance in the matter.

Regards,
