[HOWTO] Compiz + Emerald

[Pse]

Thanks to the recent efforts made by the Beryl and Compiz communities, who are willing to work closer and closer together, it is now possible to run Emerald on Compiz =).

Step 1:
Read this post (screenies + short explanation). From there you should gather that there are two ways to run Compiz and Emerald together. The first one works with Compiz 0.3.6 (and lower?), which is now in Portage, and requires patching a somewhat older version of Emerald; the second option is meant to run with the development branch of Compiz (0.5.0+) but currently works only with live GIT snapshots. We will be focusing on the second option, since patching an old version of Emerald from the old SVN repos would only expose us to old bugs and hold us back.

Step 2:
Use these modified ebuilds to get both Compiz and Emerald from their GIT repositories: compiz-9999.ebuild - emerald-9999.ebuild
Put them in your local overlay under 'x11-wm'. Most deps are already in portage, but you'll probably need to set up the Gentoo-Xeffects overlay if you haven't done it yet. Unmask packages as necessary.
The Emerald ebuild has an additional USE flag which needs to be set to use it with Compiz:
