Based on your email, I found this message and thread: https://www.open-mpi.org/community/lists/devel/2015/08/17812.php which says the problem is with a conflict between libnl and libnl3, and gives a workaround, i.e. to use --without-verbs during configure. Both my cases work with this option. Thank you.
