Not exactly sure which version causes this breakage. See Bug #683430 for more details.
Current workaround: Force your way past portage not liking that portage-utils-0.64 is now only mips & s390, as it was formerly key-worded for many arches.
Infra has tested old versions of portage-utils, and found it's been broken for quite a while: 0.62 - pass 0.65 - pass 0.70 - fail 0.71 - fail 0.72 - fail 0.73 - fail 0.74 - fail
