undefined symbol: __dn_expand ???

Hey, I'm on Mandrake 7.1. I installed PHP 4.0 without any errors, using the following: ./configure --with-mysql=/usr/local/mysql --with-apxs=/usr/local/apache/bin/apxs --with-gnu-ld make make install It seemed to go fine -- no errors during installation, however, when I try to start apache I get the following error: Syntax error on line 207 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: __dn_expand ./apachectl start: httpd could not be started I've searched the internet all day, I can't find much reference on __dn_expand... I'm out of ideas so if anyone has any ideas on what might be wrong, please reply. Thanks for your time, -Jeff
