Santiago, could you try running with 

export OMPI_MCA_rmaps_base_oversubscribe=true

added to the top of debian/rules?
I think that will get it working on your test system.

I think the problem is that openmpi does not use hwthreads or
oversubscribe by default.  So your error is saying you're trying to
run 2 processes on 1 core.
