Cargo does not build (requires Cargo). This might actually be related: ​https://github.com/gentoo/gentoo-rust/issues/220

Huh. Man, I really hate when languages invent their own packaging system (that almost assuredly will be broken or at the very least cumbersome). Anyway, I don't really know what to do here.

Looks like cargo has a dependency on itself: ​https://github.com/rust-lang/cargo/issues/3437

In order to bootstrap we would need to additionally download a prior release as a binary, similar to how it is done for rust itself.

Ah, great. I'll try to get to that but if someone else has more time than I, then please feel free to fix this.

I've created a pull request for this - ​https://github.com/macports/macports-ports/pull/589.

[dbevans (David B. Evans)]

Just to note that the current unstable versions of librsvg use a combination of C and Rust libraries and thus need relatively recent versions of both rust and cargo to compile from source. This will become urgent with the next stable release.

See ​https://gitlab.gnome.org/GNOME/librsvg/blob/master/COMPILING.md

[dbevans (David B. Evans)]

librsvg stable version 2.42.0 has just been released requiring cargo and rustc to build and is, therefore, blocked by this ticket. A status update would be appreciated. Thanks.
