There are a lot of dependencies that do not exist in the AUR
(dependencies that reside in the binary repos and probably a few ones
that do not exist anywhere at all). We used to use package IDs and a
dummy package concept to fix this but just storing package names is way
better. See also [1].

Automatic notification on dependency breakage has been discussed on
aur-dev before [2] (well, sort of :p )... Still not sure if we're gonna
implement this. I'd like to avoid making the AUR send out alerts for
various stuff.
