Comment(by eborisch@…):

 There is a long list of files that both ports claim in the man pages, like
 all of the MPI_Xxxx commands in man3. I'm not sure what the thought would
 be on this. In general, one would use one or the other, not both (they
 both implement the MPI standard, which is why they have so many
 conflicting man pages.)

 I could certainly add a (defaulting to enabled) +man variant that could be
 disabled to exclude all the man pages from mpich2's installation to work
 around this. Or I could just mark them as conflicting.

 Insofar as the non man3 conflicts (listed below) I would propose that
 openmpi rename these files to match the executables that are actually
 being installed (openmpicc, openmpicxx, etc.) by openmpi.

 man1 conflicts:
 {{{
 share/man/man1/mpicc.1.gz
 share/man/man1/mpicxx.1.gz
 share/man/man1/mpiexec.1.gz
 share/man/man1/mpif77.1.gz
 share/man/man1/mpif90.1.gz
 }}}
