No, none. With the exact same configuration (encoded in the Debian package build 'recipe' for the package), I get -- on Debian: 'unable to open osc pt2pt' verbosity but a working Open MPI setup -- on Ubuntu: no verbosity, but Open MPI hangs Very puzzling. I have rebuilt many other Debian packages on my Ubuntu systems and yet to see any divergence or regression in behaviour. Needless to say, I'd like to get this work, but I do not know what to try next.
