So... I emerged DOOM3, and it tells me to copy the .pk4 files to the base directory. I'm looking at all my CDROMs for DOOM3, and well... there's no .pk4 files.
in one of the cases you or probably the doom3.ebuild maintainer is made the mistake, just copy all base.pak (not sure what was the extension of this stupid game) to the Gentoo box
in CD1,2 and 3, u must have DATA/base or /DATA/packs, cant remeber, just copy the files from this folders to your box
If u cant give advice, dont send the helpless to the HOWTO's way or Google.com way.
