How to instruct apt-get and/or synaptic to install from source code?

Question

As I asked in the title, I would like to know how to setup Synaptic or how to instruct apt-get to install/upgrade software exclusively from source. I mean, apt-get/synaptic install only pre-compiled packets. I would like to setup the "building all" like Portage in Gentoo. Is this possible? If yes, how?

You can get the source for a package with apt-get source packagename but building it and installing are separate steps — Warren Hill, Apr 24 '13 at 13:41
Warren, can you explain briefly these steps, please? at least command(s) examples. Thanks. — Tetractys, Apr 24 '13 at 13:56
@bodhi.zazen Not a duplicate, OP is asking about compiling packages from source, not about building Ubuntu from source. — Basharat Sialvi, Apr 24 '13 at 21:20
@BasharatSial Question: "I would like to setup the "building all" like Portage in Gentoo." Answer: "apt-build world" Seems very much like a duplicate to me. — LiveWireBT, Nov 01 '13 at 09:27

Apt-get doesn't work like BSD ports or Gentoo portage. You can apt-get source and debuild all of them individually, but it's not easily automate-able or built-in.

You could theoretically script mirroring a source repo, building a dependency chain, starting at the root, and building each package... but generally for the target user-base of Ubuntu, it's not worth it.
