Help: Php4.3.3 installation on RH9.

["support" <support () sitel-india com>]

Hi,   
I am installing snort on a Red Hat 9 machine according to Snort, Apache,
PHP, MySQL and Acid and using the document Install on RH9.0 by Patrick
Harper which I downloaded in the snort web site. I have a problem with
php 4.3.3. 
After the install and editing of /www/conf/httpd.conf I receive the 
following error when I try to start /etc/rc5.d/S85httpd start  
[rootlinuxmgr root]# /etc/rc5.d/S85httpd start 
Syntax error on line 231 of /www/conf/httpd.conf: 
Cannot load /www/modules/libphp4.so into server:
/www/modules/libphp4.so: 
cannot open shared object file: No such file or directory 
This is the 231 line in /www/conf/httpd.conf : 
LoadModule php4_module modules/libphp4.so 
Can anybody quickly help me to come out of the issue. How to resolve
this problem
 
Thanks and regards
Mayur Pathak
