Ffmpeg-2.6 fails to emerge with the following error:
The following REQUIRED_USE flag constraints are unsatisfied:
cpu_flags_x86_sse? ( cpu_flags_x86_mmxext )
I can fix this by including "mmxext" in the CPU_FLAGS_X86
variable of make.conf.
But my processor is a Core i7 and has no mmxext as seen
in /proc/cpuinfo:
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov

What is going on? Is the ebuild file wrong?
Looking at the ffmpeg ebuild directory, I see that only the ffmpeg-2.6.ebuild
uses the X86_CPU_REQUIRED_USE variable. Maybe the maintainer got it wrong.
