The dired dependency is wrong, since there is no such built-in
package.  "dired" is instead part of the "emacs" package.

This seems to have fixed in lusty-explorer already.[1]

I was considering if we should take some extra measures to allow these
kinds of dependencies, but honestly it seems better to just ask
package developers to get it right.

I'm therefore closing this as notabug.
