Yeah, really.  I've made several sustained attempts to reproduce that
locally, on every machine I have, without success.

It's weird, because longfin has shown that failure a couple of times,
but I've not been able to reproduce it in manual runs on longfin's host,
which makes little sense.  I'm reduced to a theory that the buildfarm
script creates an environment different from manual runs --- but I cannot
see what that would be.
