Alltid när jag kör en 'emerge -av' på ett paket som stöder sse, sse2, 3dnow eller mmx får jag se (exempelvis)
Code:
media-libs/flac-1.1.2-r3 [1.1.1] (-3dnow) -debug +doc +ogg (-sse) +xmms

eller
Code:
dev-libs/DirectFB-0.9.24  -debug -fbcon -fusion +gif +jpeg (-mmx) +mpeg +png +sdl (-sse) -static -sysfs +truetype +zlib

eller
Code:
sci-libs/acml-3.0.0  (-sse) (-sse2)

Självklart har jag dem i USE...

Hur ska jag göra för att kompilera med stöd för dessa flaggor?

Gentoo 2005.1 @ AMD64

Kan det vara så att du måste införa --newuse när du emerge:ar? Då snappar paketen upp dina nya USE-flag settings...

Se till exempel Testing 3dnow, sse, etc... och USE flag problem. De paket som har stöd för amd64 får funktionaliteten oavsett USE-flaggorna. Mplayer är ett exempel.

Ja det verkar stämma att användning av dessa USE-flaggor är inaktiverat, då stöd ändå förutsätts genom x86_64-arkitekturen.
