The ati_gatos package downloads experimental release 6 (pre 1/26/2002), as opposed to the latest, which is experimental release 11, from 3/17/2002. I don't know what has changed between the two, since documentation is sparse. All that was needed for me to fix the ebuild was to rename it, and change the file it downloads.
Created attachment 504 [details] Here is the new ebuild Changes should be obvious.
New version in portage. Thanks for the upgrade notification.
