We have occasionally had a problem like this when we set LD_LIBRARY_PATH only. On OSX you may need to set DYLD_LIBRARY_PATH instead ( set it to the same lib directory )
Can you try that and see if it resolves the problem?

However, when I go to run the example, it stalls on the MPI::Init() command: mpirun -np 1 hello_cxx It never errors out or crashes. It simply hangs. I am using the same mpic++ and mpirun version: $ )which mpirun /Users/meredithk/tools/openmpi/bin/mpirun $ )which mpic++ /Users/meredithk/tools/openmpi/bin/mpic++ Not quite sure what else to check.
