I believe that MacPorts uses debian packages as an intermediate step,
so it incorporates the best hate from both sides of the aisle (yes,
all software is hateful, Ports is software, therefore it's hateful,
some of us just find it less hateful than the alternative of building
the whole system from lego blocks).
Or is that Fink? The fact that there's two competing ports-based
systems for OS X is a third layer of hate.
Especially when the native OS X packaging scheme (bundles and
frameworks) has advantages over both, but neither of them use it.
