rust-1.51.0_1.darwin_20.arm64.tbz2 was the package MacPorts *attempted* to download. That attempt failed, because we have not produced any such package. (We do not have an Apple Silicon build machine at the moment, although we used to and hopefully will again soon.) Because the package download failed, MacPorts built from source on your system.

No idea yet. We did successfully produce an arm64 package for the previous version of rust, 1.50.0. Probably best to file a ticket with the full compressed log.

I don't see any similarity between that ticket (which was a build failure on Yosemite due to the inclusion of the legacysupport portgroup in the port, which was resolved by removing that inclusion) and your issue (undefined symbols on Big Sur on Apple Silicon).

libheif was recently changed to include a dependency on the optional library rav1l which depends indirectly on rust, so now anything you use that depends eventually on libheif, such as youtube-dl, requires rust.

Rust is ... extremely annoying for how long it takes to build and for the limited range of macOS versions it supports and the frequency with which new versions introduce build problems. I wish people would not use this programming language. Unfortunately some developers do, and to offer their software in MacPorts we have to have rust.
