 Replying to [comment:12 lukaso]:
 > This port has been broken for over a month now for one reason or
 another. It was also last broken in december 2022. Maybe it's time to cut
 `rav1e` loose? I tried to remove the dependency in the GIMP build by
 excluding it from `libheif` but it appears to be included in some other
 port that somehow I am including so that didn't help.

 Okay, just tried building `rav1e` from source. And sure enough, our port
 is currently broken.

 But let me stress that's it's very likely ''our port'' that's broken, not
 upstream.

 Why do I say that? Well, take a look at the portfile for `rav1e`, and
 specifically the crate for `libgit2-sys`:

 {{{
 libgit2-sys 0.14.2+1.5.1
 }}}

 That crate corresponds to `libgit2` 1.5.1. Whereas `git2-rs` upstream has
 released later releases, including the latest: `libgit2-sys-0.16.1+1.7.1`.
 And the latter corresponds to the latest `libgit2` release. (Per the
 `+1.7.1` suffix.) Which is what we should probably be used. Though perhaps
 one of the previous releases, corresponding to `libgit2` 1.6.x, might work
 too. Dunno without more research/testing.

 In any case, updating that crate, likely involves updating others as well.
 Perhaps that's automated via a MacPorts script somewhere? (Not a Rust guru
 here, otherwise I would have fixed this by now.)

 So I'm quite certain this is 100% our issue.

 As for downgrading `libgit2`: Simply reverting one commit isn't going to
 cut it. We'd also need to downgrade `py-pygit2`, and a number of others.
 And then rebuild every dependent - including `rust` and `cargo`, along
 with numerous other dependents. (As the downgrade would break the ABI.) So
 no, not going to happen, when it seems very clear the `rav1e` port is the
 one that needs to be fixed.
