 Viewing the available files at http://packages.macports.org/rust/, I'm
 expecting to see a binary for version 1.44.0_0 and macOS 10.12 (Darwin
 16), but none exists. Ditto for the various mirrors, so it's not isolated
 to 'packages.macports.org'.

 Binaries 'rust-1.44.0_0.darwin_15.x86_64.tbz2',
 'rust-1.44.0_0.darwin_17.x86_64.tbz2',
 'rust-1.44.0_0.darwin_18.x86_64.tbz2', and
 'rust-1.44.0_0.darwin_19.x86_64.tbz2' all exist (plus their respective
 checksum files), but a Darwin 16 variant does not. (Though said binary
 ''does'' exist, for earlier Rust versions.)

 Based on the various build info I've reviewed, it doesn't appear that the
 10.12 compilation failed for 1.44.0_0. Nor could I find any applicable
 bugs, apart from https://trac.macports.org/ticket/60670 - which involves
 building Rust from source, on macOS Yosemite.

 Is something failing in the build or publish, that's preventing the binary
 from being copied and mirrored? Or is there something else I'm missing?

 p.s. The rust source build - which is huge, and takes an eternity - also
 fails for me, so that's not an acceptable workaround. And would prefer not
 to have to dive into that, given that the binary should arguably exist.
