Comment (by cal@…):

 It seems there is a number of problems with your state of Haskell
 packages:
  - There are lots of older versions of some packages still installed, e.g.
 you have five different versions of http-conduit, only one of which has
 ever been in MacPorts
  - Thus, you must have used cabal or some other method to install Haskell
 packages. When you do this, cabal will re-use Haskell packages installed
 by MacPorts, but those might be removed by MacPorts breaking your
 dependency tree.
  - MacPorts Haskell packages had a bug where they wouldn't be correctly
 uninstalled and unregistered if there were dependents registered, leaving
 outdated package registrations in place. While the problem has since been
 fixed, it seems some of those leftovers are still in place on your system.
  - The last two points lead to all the missing files and missing
 dependencies in the output of `ghc-pkg check`.

 You should avoid using cabal to install Haskell packages and use the
 MacPorts port where possible. MacPorts Haskell package upgrades might
 break packages installed manually using cabal.

 It seems a lot of the broken packages are in your user tree. Please attach
 the output of `ghc-pkg --global list` and `ghc-pkg --global check` so I
 can check whether you need to modify any packages installed system-wide or
 whether the problems are caused by your user packages only.
