svn merge -r 19823:19821 https://svn.open-mpi.org/svn/ompi/trunk ./ I copied the config directory in another location, and the original .svn directory was replaced by the Open MPI one ... As a result my first commit, applied the changes on the Open MPI trunk instead of the other project. This commit was SVN r19824.
