Comment (by libsystem-ethan):

 This is caused by a bug in Meson
 (https://github.com/mesonbuild/meson/issues/3493). Until a new release of
 Meson is made, running `sudo -H pip3.6 install
 git+git://github.com/mesonbuild/meson.git` will install Meson from it's
 GitHub HEAD which has a fix for this issue. After running `port clean
 graphene` the build should succeed. You ought to make sure you run `sudo
 -H "pip3.6 uninstall meson; port uninstall meson"` to remove all instances
 of meson from your system, as installing from Pip may overwrite parts of
 MacPort's Meson port.
