That is not an error, haddock just tells you that it doesn't know where the docs for base are. If you want to run haddock by hand, and that it links the docs, you must pass a lot of --read-interface=xxx.haddock flags on the command line. Also, to generate output, you have to tell it which sort of output, AFAIR, -h produces HTML, another option is --hoogle. But I find it easier to let Cabal deal with haddock, make a Cabal package, runghc ./Setup.hs configure --user --prefix=$HOME runghc ./Setup.hs haddock --hyperlink-source

If you use a Cabal package in conjunction with cabal-install it saves you even more typing: cabal configure cabal haddock --hyperlink-source
