In my copy of GHC and Cabal [1,2], you can now install multiple copies of a package with differing dependencies to the package database, i.e. q-1.0 compiled against p-1.0, and against p-2.0. The packages in the database are distinguished via a *package key*, which is an md5 hash of the package id (e.g. q-1.0) and the sorted list of the package IDs of the transitive closure of dependencies (e.g. p-1.0 or p-2.0).
maybe a stupid question, but how does the package key relate to the hash that "ghc-pkg" shows for package?
