I am afraid that baby has been neglected recently and is not tested in nightly builds. If you want to make a git pull request with your fixes to get the scripts running that would be great. I'll try to reproduce your problems; maybe a bad interaction related to threads, did you build PETSc with threads? Likely first try it without threads.
