Richard: How can we sort out the differences between the build
environment that Martin uses versus what the autobuilder is showing?

There's nothing particularly complex happening during that build,
it's a checkout and generation of a config.

I'm unable to reproduce any of the failures, and neither is the
autobuilder.

I've stared at the code and can't see what could cause any of this.

That being said, I think I have a solution to what Martin is reporting
here, where I've changed the way the meta data is maintained and
build.

It will be ready in a week or so, so I'd be interested in us holding
on anything drastic until we can try that out.
