With the huge popularity of Macs in recent years and the reputation for stability that OS X has garnered, how in the world has it happened that no one has ever written a comprehensive package manager for OSX? When you consider that in all intents and purposes, it's still a unix variant, I find it almost shocking that no one has even ported a linux package manager to work with OS X. How great would it be to have apt-get for mac? That would be a dream; synaptic or one of the many other GUI managers would be a huge welcome to an already fine OS. I just find it really strange that no one has already done this.
