General :: Error When Configuring Apache 2.2 And Php 5.3.2 On RHEL5

i am in the process of installing apache 2.2 with php 5.3.2, my problem is that after installing and configuring them , this important module libphp5.so is no where to be seen under /usr/local//apache2/modules/, so when i attempt to start or stop apachectl , i get the following errors ..

httpd: Syntax error on line 54 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server: /usr/local/apache2/modules/libphp5.so: cannot open shared object file: No such file or directory

this is how am loading the module in httpd.conf

#LoadModule php5_module modules/libphp5.so

why isn't this file there . is there a way i can get this to work
