For Debian, I think a nice solution might be to have a package of the library building software which includes a way for implementation and library packages to register with it. Then, when a new library is installed it would be rebuilt for any implementations installed and registered, and when GHC is upgraded it would rebuild all the libraries installed and registered. This nicely solves the problem of changing binary formats. The only subtlety I can see is making sure things get built in the right order when installing multiple packages at once.
This sounds a lot like the Common Lisp compiler system. I don't know much about CL, but I do know that when I had SBCL installed for a brief while, if I updated a CL library, it would recompile the library for SBCL. This is obviously a bit different than Haskell, since SBCL uses an Image file that must be updated periodically to use the new functionality, but perhaps we could make a similar mechanism for Haskell. -Brent
