Oh, here's another thought:  if we standardise the locations of as many
libraries as possible, then it becomes reasonable for a compiler to do
this:

	$ nhc foo.hs
	nhc: module `Foo' imports `Lang.Concurrent', which is a
      Haskell language extension not supported by this compiler.

	$ ghc bar.hs
	ghc: module `Bar' imports `Graphics.UI.Gtk' which is not
	installed. It may be obtained from "http://www.foo.bar.com".

Cheers,
