1 Ffmpeg-2.6 fails to emerge with the following error:
2
3 The following REQUIRED_USE flag constraints are unsatisfied:
4 cpu_flags_x86_sse? ( cpu_flags_x86_mmxext )
5

7 I can fix this by including "mmxext" in the CPU_FLAGS_X86

23 uses the X86_CPU_REQUIRED_USE variable. Maybe the maintainer got it wrong.
