Could somebody remind me what is the proper solution for the following ffmpeg issue (which blocks world updates for me)

The following REQUIRED_USE flag constraints are unsatisfied:
cpu_flags_x86_ssse3? ( cpu_flags_x86_sse3 ) cpu_flags_x86_sse? ( cpu_flags_x86_mmxext )

My CPU (Intel dual core circa 2008) has ssse3 and sse flags, but not sse3 and mmxext

Code:

cat /proc/cpuinfo

....
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good nopl aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida dtherm tpr_shadow vnmi flexpriority
....

The package app-portage/cpuinfo2cpuflags provides the cpuinfo2cpuflags-x86 command which will decode /proc/cpuinfo and provide the settings for CPU_FLAGS_X86.

You do have sse3 that is what pni in /proc/cpuinfo means.
