I think that Gentoo needs documentation on how to install/set up apache with SSL/PHP. It should also explain how to set up multiple virtual hosts all with SSL.
you can only do 1 SSL per IP so if you're doing vhosting with many domains on 1 IP, you cant do SSL + vhosting
thanks for clarifying that. But I still think that gentoo needs an Apache server documentation. Also on howto install e.g. Mysql with innodb and the like
that's a different issue ... try the forums and/or http://gentoo-wiki.com/
