GRASS 7.2 fails to install on Mac OS X Sierra 10.12.2

[P Kishor]

I get the following message: :error:patch org.macports.patch for port grass7 returned: sed: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/gis/grass7/files/patch-libraster_gdal_c.diff.tplt: No such file or directory

The final 50 lines from the log are shown below. Any suggestions appreciated.
