Comment (by Schamschula):

 I had a look at the Homebrew Formula. See: https://github.com/Homebrew
 /homebrew-
 core/blob/78fd5faf3c86b92bf7ec68e038eaac0acf3a9e59/Formula/r/rust.rb

 A noticed couple of things:

 1) there is no {{{rust-bootstrap}}} port, rather they fetch cargo
 bootstrap from https://static.rust-lang.org/

 2) they patch src/bootstrap/compile.rs

 FreeBSD has a Makefile for both {{{rust-bootstrap}}} (1.74.0 as I write
 this) and {{{rust}}} (1.74.1), however, the {{{rust}}} Makefile calls out
 version 1.73.0 for the bootstrap compiler.
