Quick question: how do I build Haddock from the darcs repo? Long version: Using Cabal as provided with ghc-6.4.1 gave me this error: $ ghc-6.4.1 --make Setup $ ./a.out configure --help a.out: Line 12: Unknown field 'data-files' So I tried to upgrade Cabal to a newer version. Following the instructions to the letter, there was some weirdness with compiler versions, but I did end up with a newer Cabal: $ cd cabal-1.1.3 $ ghc-pkg-6.4.1 unregister Cabal Saving old package config file... done. Writing new package config file... done. $ vi GNUMakefile # edit HC=ghc-6.4.1, HC_PKG=ghc-pkg-6.4.1 $ make install mkdir -p dist/tmp ghc-6.4.1 --make -Wall -fno-warn-unused-matches -cpp -i. -odir dist/tmp -hidir dist/tmp Setup.lhs -o setup ... ./setup configure --ghc --prefix=/usr/malcolm/local Configuring Cabal-1.1.3... configure: Using install prefix: /usr/malcolm/local configure: Using compiler: /grp/haskell/bin/ghc # this is wrong configure: Compiler flavor: GHC configure: Compiler version: 6.2.2 # eek! this is wrong configure: Using package tool: /grp/haskell/bin/ghc-pkg # this is wrong too ... ./setup install Installing: /usr/malcolm/local/lib/Cabal-1.1.3/ghc-6.2.2 & /usr/malcolm/local/bin Cabal-1.1.3... # installed for wrong compiler Registering Cabal-1.1.3...

There genuinely is no module called Paths_Haddock. Regards, Malcolm
