If I understand it correctly all libraries need to be reinstalled and executables can stay. Is naming convention designed in such a way that "pacman -Qs haskell" should get the same result as "pacman -Qi ghc |grep '^Required By'"?
Not quite. How about `ls /usr/share/haskell/`? All cabal2arch packages add a directory there
Ok, so the most safe way is taking "ghc-pkg list" except the packages distributed with ghc. This means a "database" of packages which were distributed with ghc (for each of its versions which existed on archlinux) would need to be maintained. For example the list of package.conf files from previous versions of ghc is such a database. But we really need only the pristine (as installed) package.conf for the ghc version we are going to replace. What about adding some commands to ghc installation which would store-off a copy of package.conf file. Then we could write a script which tells what needs to be recompiled with a new ghc version. The second best is probably to take "ls /usr/share/haskell" since almost all haskell packages are distributed with cabal. Peter.
