Do I have to compile every packages again if I upgrade ghc ? It is a pleasure to make use of the utilities (greencard, HOpenGL, etc). But what When I try to use CVS repository and stand-alone binary distribution together (because I wanted to see hdirect is like and v 0.16 does not work with ghc-5.xx) I felt very much discouraged. What should I do ? Do I always have to compile everything from the fptools source again ? I hope FFI related Haskell module gets stable and standardized soon. -- Ahn Ki-yung
