Stow seems to have a flavor of Mac homebrew about it (more likely the other way around) everything is compiled and installed into `/Library/Cellar` and then symlinked into the system path, you can `brew unlink readline`, for example and it goes away, link it back and it's available to the system again. The `brew` executable knows about the correct flags to give to `--configure` within it's own context, so it rarely goes wrong.
