an ebuild is just a script! it's not a package :-)
ok, no ebuild possibility...... but even with fglrx 8.5 i still get the ghost-model, what can we do for it?
The ATi shader issue seems to be gone now with the BETA client. So it will be fixed with the release with FCP 2.
You can see for your selfs:
Savage2TestInstall-1.4.10-i686.bin (md5sum 4f8a758f3db1fe0e404f9920a744083e)
Savage2TestInstall-1.4.10-x86_64.bin (md5sum 780dd91c9c349c31f17ca8de7630b9bb)
Remember to update the client with the ingame update tool. (Just click on login an say that you already have an account)
