AKA switch to gentoo
The stuff in "arch" is fairly long in the tooth. The stuff in "~arch" is maybe on par with what Ubuntu and OpenSUSE shoved out of their last release.
I know about layman... I'm running the x11 overlay on my laptop (X1300 video card, if that doesn't explain it). Maybe I'm doing something wrong, but it doesn't seem like there's been that much activity with that overlay. I sync my portage tree and the overlay every few days, and x11 has told me I've been up to date for the past three weeks.
Or did you just mean that with a Gentoo system, most everything you'd need for a build environment is already there from the word "Go"?
