hamerkop is still failing in its runs done today.  However, I'm not sure
that that proves anything about our hoped-for fix, because the commit SHAs
it's showing on the buildfarm status page are still from Oct 13.  It looks
like hamerkop has failed to pull any git updates since it was migrated to
the new buildfarm script version.
