Rust build

[Mark Bestley]

I have just done a port seflupdate and upgrade outdated.

Rust was needed but it had to be built on my machine as there was no suitable version on macports.

I am on a Mac Mini M1 running macOS 12.5.1 and rust should be 1.61.0

Now the web page <https://ports.macports.org/port/rust/details/> says that it has built, in fact a month ago. But live check has failed.

Why is rust not available?
