FWIW, a neat trick to help with this is to encode part of the soname
of libstdc++ in the soname of your library when you build it. The main
observation is that any ABI/compiler/etc differences must be already
taken care of by libstdc++'s soname versioning policy.  Then you can
have parallel installations of MPI libraries without too much trouble.
