Sorry for the previous message. I am sending it again. Dear fellow haskell programmers, I tried to install a package in hackageDB and got a strange error from haddock: haddock: internal Haddock or GHC error: Maybe.fromJust: Nothing Here is the complete log: http://hackage.haskell.org/packages/archive/HXQ/0.10.0/logs/failure/ghc-6.8 When I build it using Cabal 1.6.0.1 and haddock 2.2.2 using 'runhaskell Setup.lhs haddock', it works fine (I get warnings but no errors). Also haddock 2.3.0 is not available in hackageDB so I can't test it myself. Where I can find haddock 2.3.0? Thank you for your help, Leonidas Fegaras _________________________________________________________________ Stay organized with simple drag and drop from Windows Live Hotmail. http://windowslive.com/Explore/hotmail?ocid=TXT_TAGLM_WL_hotmail_102008
