The problem here is that buildbot tries to delete directory with 444
permissions. That's going to fail on both Solaris and OpenBSD. My
assumption is that it runs well on Linux, but on Unix you probably need
writing permission for it. Perhaps test suite might be fixed when
creating and testing with 444 perms directory to chmod it later to
writing mode? Or that's my feeling about this issue so far w/o any
further investigation except looking into the problematic directory.
