Comment (by mascguy):

 Lukas, I'm making progress, relative to updating `rav1e` to use the latest
 version of `libgit2-sys`, etc. (It simply required some time to review how
 dependencies are handled within the Rust/Cargo space.)

 Presently dealing with compilation failures related to `libssh2`, but will
 figure it out with enough time.

 So hopefully this port will be fixed in the next few days, and you won't
 need to remove it from the mix long-term. Stay tuned...
