I have managed to get an ebuild for gentoo to install ion3-20080207 (the latest, according to the website).
It will also install the mod_xinerama module that was posted on this list a while ago, if you specify both "xinerama" *and* "unsupported". http://gentoo-wiki.com/HOWTO_Installing_3rd_Party_Ebuilds tells you how to add the ebuild into your portage system. -- Jarrod Lowe
