Comment (by ryandesign):

 Remove the line `github.tarball_from releases`. This GitHub project has
 not published any releases, only tags.

 Remove the lines `distfiles v${version}.zip`, `master_sites
 https://github.com/cavaliercoder/dmidecode-osx/archive` and `use_zip yes`
 to let the github portgroup's defaults be used. The checksums of the
 distfile will change, so update the `checksums` lines.

 Remove `This is an OS X native port of dmidecode` from the description and
 long description; it's understood that software in MacPorts works on
 macOS.

 Change the `maintainers openmaintainer` line. Either add your obfuscated
 email address if you want to be the maintainer, or use `nomaintainer` if
 you do not. `openmaintainer` by itself is invalid.

 Because you use `use_configure  no`, you're responsible for ensuring the
 right compiler and `-arch` flags get used. See UsingTheRightCompiler.

 Use only spaces, not tabs.
