Created attachment 296871 [details] output including traceback I get "AttributeError: 'FakeVardbapi' object has no attribute '_aux_cache_keys'" from emerge -uDNa on one of my machine. I cannot reproduce it on the other machine; though portage version is same on both Macs, other conditions such as installed packages are obviously different.

let's see if Zac has an idea.
See bug #395879.
Right. It seems the same issue. The error was triggered by ambiguous "gentoo-syntax"s. If you have already installed one of them, no error is triggered. That explains my situation.
ah, thanks, I'll bump soon.
