While looking at this: can anyone build rust from pkgsrc-current?
It fails for me early with:

# /usr/pkgobj/lang/rust/work/rust-bootstrap/bin/cargo build --manifest-path
/usr/pkgobj/lang/rust/work/rustc-1.29.1-src/src/bootstrap/Cargo.toml --frozen
error: failed to parse manifest at   
`/usr/pkgobj/lang/rust/work/rustc-1.29.1-src/src/tools/clippy/Cargo.toml`

Caused by:
  the cargo feature `edition` requires a nightly version of Cargo, but this is t
he `stable` channel 


And the file starts with:

cargo-features = ["edition"]

[package]
name = "clippy"
version = "0.0.212"



The rust bootstrap kit for sparc64 is rustc 1.29.1, but cargo is 1.29.0.
