--->  Some of the ports you installed have notes:
  hdf5 has the following notes:
    Mac users may need to set the environment variable "HDF5_USE_FILE_LOCKING" to the five-character string "FALSE" when accessing network mounted files.  This is an application run-time setting, not a configure or build setting.  Otherwise errors such as "unable to open file" or "HDF5
    error" may be  encountered.
