Given the hundreds of commits to the build system and its complexity, I'm
in awe this doesn't happen more often. Heck, I've done an order of
magnitude fewer commits to the build system and broken it more often than
you have, and that's when it was a much simpler beast than it is today.

Steve's just being overly grumpy imho.  Accidents happen despite one's best
efforts. This is -current after all...
