Can't build package (v0.1.2, Julia 1.4.1)

[evanfields]

I'm unable to build H3 on Julia 1.4.1 / macOS in a clean environment with nothing else. I didn't see any installation instructions in the readme, so I assume the package manager is the preferred installation method. Build error and versioninfo:
