Re: [Haskell-cafe] Problems with haskell98 package in GHC

Looks like you've done a global install and thus have overwritten the original. I'm afraid that means you have to reinstall GHC, I know of no way to fix it.

Thank you for the explanation. Fortunately, the old version was still there in its own folder, so was able to unregister the new one and re-expose the old.
