Live-git packages for much of X.Org (the important parts, anyway) are now available in Gentoo’s x11 overlay, thanks to James Cloos. I hope you’re all very happy that he’s merged his work into the main project overlay–I know I am. Gentoo users can add this overlay by installing layman and running `layman -a x11`. All the live-git packages are in package.mask, so you’ll need to unmask them–portpeek is one easy way of doing this.
xorg-server-1.5 prereleases are also in there. So far that’s just 188.8.131.521, but more should show up soon. They’ll remain in the x11 overlay until they build against packages that have actually been released, at which point they’ll move to package.mask in the main tree. Any xprint users, feel free to contribute patches to fix its build. I know Debian already has some patches for this, so that would be a good place to start.
