Comment (by basmac):

 {{{
 Thanks for all the help, I think I now have it built on Sierra and will
 try and reproduce on El Cap -
 could not install grass7 so install explicitly grass
 could not install QGIS with +qt4 -qt5 +grass as suggested
 uninstall py27-qscintilla2
 remove all inactive installs
 install qwt61 +qt4 -qt5 (has to have -qt5)
 install QGIS no options
 requires port -f activate QGIS

 So now I have
 [mac27:/opt/local/lib] root# port installed grass
 The following ports are currently installed:
   grass @6.4.3_5+python26+wxgtk28 (active)
 [mac27:/opt/local/lib] root# port installed qwt61
 The following ports are currently installed:
   qwt61 @6.1.3_0+qt4 (active)
 [mac27:/opt/local/lib] root# port installed QGIS
 The following ports are currently installed:
   QGIS @2_18_6_0+postgresql96+qt4 (active)
 [mac27:/opt/local/lib] root#
 }}}
