FYI, I was able to successfully compile nightly build openmpi-v1.8.4-134-g9ad2aa8.tar.bz2 on Ubuntu 15.04 with the latest dev packages (as of today) and --with-pmi-libdir=/usr/lib/x86_64-linux-gnu Thanks, -- Lev Givon Bionet Group | Neurokernel Project http://www.columbia.edu/~lev/ http://lebedov.github.io/ http://neurokernel.github.io/
