 Please note that you then need to activate atlas:
 {{{
 sudo port -v configure grass7 +atlas
 }}}
 But it fails with the following test which I didn't investigate further:
 {{{
 configure:10856: checking for dsegv_
 configure:10882: /usr/bin/clang -o conftest -pipe -Os -arch x86_64

 Undefined symbols for architecture x86_64:
   "_dsegv_", referenced from:
       _main in conftest-wB0muu.o
 }}}
 Note that google "autocorrects" the search for `dsegv` into `dgesv`, so
 this could be a typo in `configure.in` in grass7.
