using emerge in ubuntu and compiling source

[LSparky]

can ubuntu be used with emerge?
can i build packages from source with apt-get?
can i easily compile ubuntu kernel and system on my computer?

There is a package called 'build-essentials' and you can either install from the repositories or from generic tarballs. There are also packages to compile a custom kernel from sources. Do a little research in the internet.

By the way you won't want to use 'emerge', as this is for portage/ gentoo only.
