I'd normally expect to install in parallel directories under /opt, in which case that's not really a problem. > Does that make sense? Not all, without looking at the link, but I'm glad it is being dealt with, thanks. > Check out our wiki page about the shared library version numbering: > https://svn.open-mpi.org/trac/ompi/wiki/ReleaseProcedures.
