Comment (by mboes):

 It turns out that because `base` is a "wired-in package", it's magical.
 GHC doesn't use versions to locate wired-in packages, because they are
 assumed unique. That's why the above example works. But in the general
 case, it won't.

 So I guess we should close this ticket - at any rate there's no issue with
 ghc-pkg, but perhaps we want to consider having GHC accepting just package
 names in the pkg db when they are unambiguous.
