LAMP Server setup help

Hey, I have setup a test system on my home network in the past to develop & test PHP apps by installing an ISAPI PHP dll in IIS. It worked great but now I trying to setup a LAMP server on Debian/Lenny. I ran the following command; aptitude install apache2 php5 libapache2-mod-php5 But got the following error message; Setting up apache2-mpm-prefork (2.2.4-3) ... Starting web server: apache2apache2: Syntax error on line 187 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/httpd.conf: Cannot load /etc/apache2/modules/libphp5.so into server: /etc/apache2/modules/libphp5.so: cannot open shared object file: No such file or directory failed! invoke-rc.d: initscript apache2, action "start" failed. The error is pointing to this line in the httpd.conf; LoadModule php5_module modules/libphp5.so But this directory or file don't exist in the /etc/apache2 directory. Not sure how to fix this. I'm a newbie when it comes to the LAMP server apps. Any help would be appreciated. Thanks, Randy
