Additional context

Thanks for rasing this issue @squillace . make build-c is actually not ran by the CI/CD so its currently broken. I will take "adding make build-c to CI" as a follow up

But to just fix the issue you ran into - please make sure that you have wit-bindgen tag v0.2.0 installed instead of the latest wit-bindgen

[mboersma]

cargo install --git https://github.com/bytecodealliance/wit-bindgen \
  wit-bindgen-cli --tag v0.2.0

Maybe that should go the docs somewhere? Took me a bit to figure out the right incantation.
