[Haskell-cafe] haddoc "modules on this system" index

I have a bunch of dead links in file:///Users/anatolyy/Library/Haskell/share/doc/index.html like this one: file:///Users/anatolyy/Library/Haskell/ghc-7.8.3-x86_64/lib/blaze-builder-0.4.0.1/doc/html/Blaze-ByteString-Builder.html which should really be this one: file:///Users/anatolyy/Library/Haskell/ghc-7.10.1-x86_64/lib/blaze-builder-0.4.0.1/doc/html/Blaze-ByteString-Builder.html is there a way to regenerate the index from the currently installed docs?
