It led to an ugly failure (see below). I took it off my path, cleaned, configured, and the build (so far) went better. I checked the version it was picking up, and it was 3.16. So configure might want to check for this. (Why is this crap on my path? I no longer remember, it has been there for almost ten years, and whether pkg/gnu appears on any given machine is hit-or-miss.)
