What, precisely, requires that, at least if you can recompile the MPI
program with appropriate options? (Presumably it's features of the
Fortran/C interfacing and/or Fortran runtime, but the former may be
influenced by compilation options, and I'd hope the glue didn't require
the compiler runtime -- the Intel compiler is on the list to check.)
It's obviously of interest to those of us facing combinatorial explosion
of libraries we're expected to install.

Also, is there any reason to use mpi-selector rather than switcher?
