This is just an argument against <i>bad</i> package managers. Good ones will offer binary packages by default, but allow you to tweak (or just pass .&#x2F;configure options to) an installation formula, at which point they&#x27;ll switch over to pulling in the source package, applying your changes to it, building it, and installing the result, while still offering you full package-level management of the result (including having the package satisfy deps correctly.)
