Someone else already brought that up and I addressed it I recommend scrolling down a bit and you ' ll find the reply . <| sep |> So is TK out the rest of the game now ? <| sep |> that wasnt even a boarding lmao <| sep |> Okay , your problem is this The following REQUIREDUSE flag constrain are unsatisfied cpuflagsx 86 sse ? cpuflagsx 86 mmxext Those lines tells you that some use flag requirements for a packages are not met . Specifically in this case it tells you if cpuflagsx 86 sse is set cpuflagsx 86 sse ? then cpuflagsx 86 mmxext must be also set for this package . In other words . you can ' t just have the sse CPU extension enabled . you also need to enable the mmxext extension . But afraid in this case it gets a tiny little bit more complicated as CPU extensions are handled in a special way in gentoo nowadays . Sure . you could just enable cpuflagsx 86 mmxext as useflag and it would probably solve it . but that ' s not how it is done anymore . Have a look for how to best set the possible CPU extensions your processors allows Basically installing cpuid 2 cpuflags , running it and using the output to add a CPUFLAGSX 86 line to etcportagemake . confedittypos
