Error using `create_app`: 'uv.h' not found (on OSX)

TL;DR: create_app is erroring for me using the official Julia 1.3.1 binaries, saying that it can't find uv.h (#included in src/embedding_wrapper.c, line 9).

/Applications/Julia-1.3.app/Contents/Resources/julia/include/julia is properly included in the file path, but strangely (to me) there are no header files in there. Are they supposed to be included in the official binary distributions?

Context: my computer died, so I started from a fresh install of Julia 1.3.1 using the official binaries. It worked fine on my previous system, also (as far as I remember) using the official binaries.

$ julia -e 'using PackageCompiler; create_app(".", "./build", app_name = "collect_samples", precompile_statements_file = "precompile/precompile.jl", force=true)'
