NetBSD's gone in a slightly different direction, they have something called pkgsrc, which brings a BSD-ports-like tree to a wide variety of different platforms and operating systems (..including OS X and some others).
It seems they provide binary packages for a few systems as well, primarily I'm assuming people would build things themselves.. but it appears they tag their source tree with quarterly releases, so I'm assuming packages would target this and be slightly outdated?
You can find out more on their website:
