Recompile your own version of openmpi in a local directory, set your PATH to your local openmpi install.

export PATH=/my/openmpi/install/include:/usr/local/include

mpicxx -show

Just specify where each individual MPI distribution's stuff is on the
command line when you compile with mpicc *.c -I$MPICH_HOME/include or
mpicc *.c -I$OPENMPI_HOME/include where the "HOME" directories were
specified with --prefix= when you installed.  Hope this helps.  This
works for me.  Hope this helps.  Cheers!
