[Haskell-cafe] Problem with Hyperlinking Haddock-documentation

Maybe somebody can enlighten me. When I run haddock and put the html files e.g. in directory ~/bar/foo, any references to things defined in the Prelude or the libraries are linked to, say ~/bar/foo/Prelude.html#t%3AFractional, which of course does not exist, because the documentation for the Prelude is elsewhere. How can I tell haddock to link such references to where Prelude.html actually is? Please be aware of the fact that I know ///very/// little about html, hyperlinks and such, so be detailed and don't presuppose much. Thanks, Daniel
