Rustfmt: Using the latest nightly via multirust, rustfmt can't load some dynamic libraries

$ git clone https://github.com/nrc/rustfmt

$ multirust update nightly
$ multirust override nightly
$ cargo build --release
$ sudo cp /target/release/rustfmt /usr/local/bin/rustfmt (on $PATH)

cargo test works fine, which is weird.

This is a problem again now that rustfmt has gone back to nightly. See #1707.

Same here. cargo test output:

Result of trying to run rustfmt (identical results for debug and release builds):

rustc 1.5.0-nightly (20a6938c0 2015-10-16)
cargo 0.6.0-nightly (18e496a 2015-10-17)

I'm running on a 2012 rMBP with El Capitan 10.11.0.

iirc, this is an issue with Cargo and OS X, although I'm not sure exactly what. Would be good to fix at our end if we can.

Seems it's not OS X specific, I'm also hitting this on Linux.

Rust libraries are linked dynamically to rustfmt, for whatever reason:

I believe it's the actual cause of the problem.
