Gentoo is not about ease of use or making installation easier for the new user. Computers are what you do with them, and most users have little or no knowledge of how their systems are put together, and care even less. Gentoo is for the users who want to reach under the hood, get their hands dirty, and learn.
Installation is hands on, and slow and painstaking, but is worth the effort if you have the time and the inclination to work your way through the Gentoo Handbook, and don't mind waiting while the code compiles.
As one comment in the Gentoo forum puts it: "The nice thing about Gentoo is all you have to know how to do is read. Most of the errors tell you what the problem is. After that it's a matter of a quick Google search and then fixing the error..."
"Programming is irrelevant. You will be assimilated."
Rest here
