Andrew Lamb commented on ARROW-9628:
------------------------------------
I looked into the build failure and also couldn't reproduce it or really
understand it yet.
What is really strange is that the standard output of the failure,
https://github.com/apache/arrow/runs/937976656, reports that prost-derive
v.0.6.1 was actually downloaded a few lines prior to the error that
prost_derive can't be found:
```
...
Downloaded prost-derive v0.6.1
Downloaded net2 v0.2.34
Downloaded memchr v2.3.3
Downloaded futures-task v0.3.5

Downloaded http v0.2.1
Downloaded futures-channel v0.3.5
Downloaded bytes v0.5.6
Downloaded autocfg v1.0.0
Downloaded heck v0.3.1
Downloaded aho-corasick v0.7.13
Downloaded fnv v1.0.7
Downloaded futures-io v0.3.5
Downloaded base64 v0.11.0
Downloaded dirs v1.0.5
error[E0463]: can't find crate for `prost_derive` which `tonic_build` depends on
--> arrow-flight/build.rs:36:9

36 | tonic_build::compile_protos("../../format/Flight.proto")?;
| ^^^^^^^^^^^ can't find crate
error: aborting due to previous error
```
I couldn't quite figure out where
https://github.com/apache/arrow/runs/938082881 actually ran Clippy.
My next step will be to try and reproduce the error via CI
> [Rust][DataFusion] Clippy PR test failing intermittently on Rust / AMD64
> MacOS
