[petsc-users] [petsc-maint] PETSc () -- MPI -- Versions Conflict on Mac 1

[Barry Smith]

   Send the output from 

   otool -L  libdeal_II.g.9.3.0.dylib

    otool -L libslepc.3.15.dylib 

    otool -L libpetsc.3.15.dylib 

    You will need to find the directories of these libraries and include them in the otool command.
