I think I know what is going on now. The source of the problem seems to be a bug in your Portfile, and not an issue on our side.

I'm not familiar with how the GitHub handling works exactly, but
---
github.setup        D-Programming-Language dmd 2.066
---
seems to suggest that it fetches the "2.066" branch. This is not a good idea, because further point releases are also prepared there, as Kenji already mentioned. Instead, please use the actual release tag, e.g. "v2.066.0".

Best,
David

Dear DMD developers,

Thank you for developing DMD.
I maintain dmd and related packages of MacPorts.

We noticed a few updates to v2.066.0 of dmd, druntime and phobos
without changing their tags in the git repository (releases).

<https://github.com/D-Programming-Language/dmd/releases>

We call such updates `stealth updates'.
The checksums are verified to make sure that the correct source code
have been downloaded by MacPorts' port command.
The checksums are written in the package description file, called Portfile.
We need to special treatment for stealth updates.

<https://trac.macports.org/wiki/PortfileRecipes#stealth-updates>

From the viewpoint of package maintainer,
stealth updates are not a good idea.
I understand that the changes are for bug fixes or enhancement.
But if so a new version number (e.g. v2.066.1 or v2.066.0.1)
or a tag should be given to the commit.

I appreciate if you discussed my suggestion among the developers and
considered adopting it.

Regards,

Takeshi
