Problems with DSO
If you get the mod_perl binary package (i.e. RPM) and it doesn't work, try and get a static install to work. mod_perl DSO does not work reliably. If mod_perl is compiled statically into Apache, it just works, and you don't need to configure the web server with anything, and you'll probably need to comment out lines like "LoadModule ...".
META: Not clear on last sentence -- are you saying that if you have a static version people will have to comment out lines or they won't? If they will then the text is correct, if the won't then it should be: "...server with anything, and we shouldn't even need to comment out lines..."
