apache2 php5 error

[Paul Cartwright <debian@pcartwright.com>]

I know I've had this error before, but I can't remember what fixed it. I've 
tried purging apache2 & php5, and reinstalling, same error..
there is only 1 httpd.conf file under /etc and it is /etc/apache2/httpd.conf 
and it only has 1 line with libphp in it..

 
paulandcilla:/etc/apache2# /etc/init.d/apache2 restart
Restarting web server: apache2[Tue Aug 17 15:55:42 2010] [warn] module 
php5_module is already loaded, skipping
[Tue Aug 17 15:55:42 2010] [warn] module php5_module is already loaded, 
skipping
 failed!

from httpd.conf:
LoadModule php5_module        /usr/local/apache2/modules/libphp5.so

ls -l /usr/local/apache2/modules/libphp5.so
-rwxr-xr-x 1 root staff 12580660 Mar  2  
2009 /usr/local/apache2/modules/libphp5.so


help?
