In the past, I've been able to resolve issues similar to this one

by flushing the animal's git repo (rm -rf pgmirror.git) and letting

it pull that down fresh on the next run. Not clear if you included

that when you "removed the buildroot"?

Yes, I did "rm -rf buildroot". After that, I verified (with "diff -r") that I had no changes

vs. the distribution tarball other than having my build-farm.conf present.

Don't do that. All the state is stored under the buildroot, and you'd be throwing that away. 999 times out of 1000 this should do the trick:

rm -rf buildroot/[RH]*/pgsql

The other 1 time out of 1000 you could also remove the mirror like Tom suggests as well.

Thanks, I’ll keep that in mind if this ever happens again. However, removing those things didn’t fix the problem. I suspect there

might be something wrong with the Perl setup on that animal, even though it hasn’t changed recently. Unfortunately, my Perl

skills are non-existent, and I have no clue how to proceed.
