> On a Mac, there is no system-blessed pacakage manager ... Which is one very big reason why commandeering /usr/local for a single package manager is inappropriate; it means that your 3rd-party package manager cannot share the system with any other 3rd-party package manager. To re-iterate -- the BSD team, who maintained hier(7), very intentionally didn't put MacPorts in /usr/local.
