The package management is weird. It makes sense, but it is weird they go into more detail with dependencies like "enhances" or "enhanced by" and other stuff. It is a more complex graph, and lends more to discovery, which is cool, but it through me for a loop for a second. You can still (after a bit of perusing the model) figure out what concrete dependencies are, but there are some packages that do some circular weirdness. There is also still somewhat of a binaries problem for the various flavors of Mac, Windows, Linux. You can get source for most things, but bubbling up of system dependencies you're on your own like other platforms, although Java & Maven seem to have a solution for distributing some binaries a little better possibly...
