recent commit breaks GUB releases

[Graham Percival]

We've had a number of relatively big internal changes, and I would
really like to have a release to make sure that things haven't
broken in the regtests or for users.

However, I cannot build GUB due to

The patch went through the countdown, so that's completely fair
and there's no blame attached to this.  But could somebody PLEASE
fix this so we can find out if anything else broke in the past two
weeks?

Cheers,
