How I Fixed It:
PyCairo requires a homebrew install of cairo and pkg-config. I've apparently previously installed cairo, but not pkg-config.
$ brew install pkg-config
$ pip install -e .
and gftools installed without problems. Happy to file a README update PR with these instructions if I am not missing something. I checked and pkg-config does not appear to be installed with XCode CL tools. Seems to require a manual install before the pip install attempt here (and for fontdiffenator alone...).
