 Still no luck on Sierra for me using the install command
 port -d install QGIS +qt4 +grass -qt5
 looks like grass7 issue now ?

 In case of errors please change into the directory with error and run
 'make'.
 If you get multiple errors, you need to deal with them in the order they
 appear in the error log. If you get an error building a library, you will
 also get errors from anything which uses the library.
