Errors on install

Hello all. I'm trying to install Php 4.0.2 on my Redhat 6.2 system. I do the standard ./configure --with-mysql --with-apxs make make install then I edit my /etc/httpd/conf/httpd.conf file and change the load module line to look like this: LoadModules php4_module modules/libphp4.so Then I add the following: AddType application/x-httpd-php .php Now after all that, I get errors when I try to start Apache. Here is the error: PHP Warning: Function registration failed - duplicate name - define in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - defined in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - each in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - strlen in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - strcmp in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - strcasecmp in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - error_reporting in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - leak in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - function_exists in Unknown on line 0 PHP Warning: Basic Functions: Unable to register functions, unable to load in Unknown on line 0 Can someone tell me what I'm doing wrong? I'm at a loss.
