SeaMonkey 2.53.5.1 compiled in Easy Dunfell

I had previously reported being able to compile SM 2.53.4 but not 2.53.5 and 2.53.5.1:

...no, it is not a glibc version problem as I first surmised, but a rust version incompatibility. I examined the build log, and saw that there were rust errors.

Running "rustc --version" returned "1.48.0", and I saw from the LFS page that they are using rust 1.47.0 to compile SM 2.53.5.1:

In Easy Dunfell, I used this method, rustup, to install rust:

https://www.rust-lang.org/tools/install

...which installs the stable version, which is 1.48.0. So, how to install 1.47.0? The only information I could find is this:

https://doc.rust-lang.org/edition-guide/rust-2018/rustup-for-managing-rust-versions.html

And I ran this:

# rustup toolchain install 1.47.0 

It downloaded, however, rust is still 1.48.0 and there is no information that I can find on how to change over to the 1.47.0 version.

So I just hacked it, dragged stuff around until 1.47.0 was working.

And guess what, now SM 2.53.5.1 compiles!

Oh dear, as rust gains popularity, are we going to have a whole new game to play, with rust version incompatibilities? This experience with SM is not good, as I already have a very low opinion of rust:
