examples wont compile

[Jack17432]

When I run cargo build on the examples on linux. I get the following error

called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }

Is there a setup that I am missing?

This is actually an error that shows up when there is no protobuf compiller installed.

Will need to have it output a friendlier error message in that case
