libphp5.so error

Hi there, I have installed php5.2.8 successfully on my suse test system. Now I want to reproduce it on my prod system, but there is an error I can't find a solution for. I compiled php and the I did run configtest on apache 1.x /etc/init.d/apachectl configtest Syntax error on line 223 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp5.so into server: /usr/local/apache/libexec/libphp5.so: symbol mysql_set_character_set, version libmysqlclient_14 not defined in file libmysqlclient.so.14 with link time reference Any ideas? I do not want to upgrade to apache 2.x. I am kind of lost right now. Thank you for any help! Best regards, Merlin
