Likewise, you'll need to install pkg-config, which can be install from brew:

$ brew install pkg-config

warning you might need curl -OL on any of the curl commands.

In your rust project, add the following dependency for Sawtooth:

sawtooth_sdk = { git = "https://github.com/hyperledger/sawtooth-core" }

also for protobuf you need to cd protobuf-all-3.6.1 before running configure && make but that's probably obvious.

If you're still having issues with your PKG_CONFIG_PATH after using homebrew to install pkg-config, might need:
$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
