The HOSTNAME setting has usually got no impact on the ports such software
is listening on or access control.

It may influence the Apache 2 defaults when you've got virtual hosting
enabled, but you need to do that explicitly, and either way, a few
ServerAlias lines in the right place should fix things up.
(I don't know Gentoo configuration layout though.)

I think HOSTNAME="arrakis.doesntexist.org" is the way to go and
HOSTNAME=localhost on the other hand is definitely wrong.

The HOSTNAME shouldn't usually be used for access control anyways, but
you'd rather use Apache directives. For tightening things up, you can
actually set the software to listen on 127.0.0.1 or bind to the loopback
interface or use Apache allow/deny and order statements. I don't know about
MySQL access control or phpmyadmin though - I personally try to steer clear
of such stuff.
