[Pkg-rust-maintainers] Bug#886651: cargo: Missing dependency on llvm to get llvm-config

[Sylvestre Ledru]

Package: cargo
Version: 0.23.0-1
Severity: normal

Hello

Trying to build https://github.com/marco-c/grcov/ using cargo
$ cargo build

It is failing on:

   Compiling rust-crypto v0.2.36
error: failed to run custom build command for `grcov v0.1.31 (file:///home/sylvestre/dev/mozilla/grcov)`
process didn't exit successfully: `/home/sylvestre/dev/mozilla/grcov/target/debug/build/grcov-c8b56ee863ef452a/build-script-build` (exit code: 101)
--- stderr
thread 'main' panicked at 'Error while running llvm-config: Error { repr: Os { code: 2, message: "No such file or directory" } }', /checkout/src/libcore/result.rs:906:4
note: Run with `RUST_BACKTRACE=1` for a backtrace.

Installing the llvm package which provides llvm-config was enough to fix my issue.
