but now are in ghc.
Thanks :) So deleting them before upgrading was the right move.

This is a problem with ghc-pkg version. For previous version of ghc I had to do:
$ pacman -Rcs ghc
then reinstall ghc and needed haskell-* packages. I think you'll want
to remove the offending files before installing ghc again. I hope this
solve the problem.
Thanks for the information. I am going to try reinstalling ghc and then all my haskell-* packages, and hopefully it will go through smoothly.
By the way, what's the progress on haskell-extra, and did you find out where haskell-old lives (in case haskell-extra still depends on haskell-old)?
