No matter. Maybe me not either.

That works for the Modules that came with GHC but not for the others in the Haskell Platform. (On the Mac with the Haskell Platform there came the GHC.framework and the HaskellPlatform.framework. In the doc folder of the GHC.framework is a central index.html in the doc folder of the HaskellPlatform, it isn't.) However, still an improvement.

I'm not that far yet with Haskell. But I mark that note for later.

I just did.

Well, there are to much to reinstall everyone per hand, but not to much if there is a magic command like 'cabal upgrade --reinstall --all' to do it all at once. Any help how to do that?
