Good. Note that the above user-config.jam doesn’t require you to set the include, lib paths or libraries. So I’m not sure why you say this:

Can you provide me an example of an Intel MPI that requires you to explicitly set the include, lib path and libraries? Intel MPI doesn’t require you to do this any more than any other MPI implementation does.

Right. Cray, for example, does not provide a separate wrapper script, and it works just fine with Boost.MPI and Boost.Build.
