[basmac]

on El Cap, no issue on Sierra for same installs, get infinite loop on ncview install/update, requests hdf5 deactivate, then keeps requesting it -

  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.

ncview is already installed, but it was determined to be broken. MacPorts does not know beforehand that ncview cannot be built with hdf5 active, but tries to fix other ports first that reactivate the hdf5 port. Please try this:

sudo port -f deactivate hdf5
sudo port -ns upgrade --force ncview
