We discussed this on IRC recently, and the options we came up with were:

* Simon's ghc-paths package

Pro: With dynamic libraries, you can move a binary to a different
     machine (with GHC in a different place) and it will work
Con: Needing to compile it on installation

* Using a Windows registry entry, or /etc/ghc.conf (along with
  ~/.ghc.conf, somewhere in /usr/local and /opt or whatever is
  standard) to get a mapping from GHC version to install location

Pro: You can move a binary to a different machine (with GHC in a
     different place) and it will work
Con: Won't work if you have multiple copies of the same version
     installed for some reason. You need to be able to write to a
     suitable ghc.conf.

* Making a magic GHC.Prim.packageConf :: FilePath, that gets baked into
  the executable at compile-time.
Pro: Simple (from the user's point of view, at least).
     Handles the in-ghci case admirably.
Con: Can't move binaries to other machines.


Thanks
