How is it done?
I know ./configure --prefix=/usr/local, but this doesn't change the root
partition, some files still go to /etc. Gentoo installs the package
first into a sandbox environment somewhere in /usr/portage/... or so.
How can I compile a package by myself, install it into a new directory
and make a package (tar.bz2) out of it?

I thought about making a server distro similar to gentoo, without the
USE flags but still highly optimized. The packages would be compiled for
each architecture on-demand on a compiler farm only when a user wants to
install it and then be saved on a disk for the case that someone else
has the same architecture and wants the same package. The distro would
be without desktop packages and multimedia support, who need that on a
server..
The user would request a package over HTTP
http://packages.distro.org/get.php?class=net&package=asterisk&version=latest
and get the URL of the compiled package or a status information on the
compilation status (estimated time left etc).

icecream (http://wiki.kde.org/tiki-index.php?page=icecream) is quite
good for a compiler farm, it even supports 'environments' for
cross-compilation.
