I've just installed the Haskell Platform (2009.2.0.2) on Mac OSX 10.5.6, including GHC 6.10.4. Then I started added some packahges with cabal install. But happstack-helpers-0.30 fails with: Happstack/Helpers/DirBrowse.hs:88:105 Couldn't match expected type `String' against inferred type `Bool' In the third argument of `hscolour', namely `False' In the second argument of `(.)', namely `BrowseHtmlString . (hscolour defaultColourPrefs False False f)' Is this a known error, and if so, is there a workaround? -- Colin Adams Preston Lancashire

I guess it's the same problem that was reported earlier this week with hlint and hscolour 1.15. I'll try installing an earlier version of hscolour. -- Colin Adams Preston Lancashire

Installing hscolour 1.14 instead did the trick. Can we have a new version of happstack-helpers that supports hscolour 1.15 please? -- Colin Adams Preston Lancashire
