Today I tried to build xmonad from the latest darcs source, and got an error message I don't understand. Here's the terminal session: drc@tangerine:~/local/haskell/xmonad$ darcs pull Pulling from "http://code.haskell.org/xmonad"... No remote changes to pull in! drc@tangerine:~/local/haskell/xmonad$ runhaskell Setup.lhs configure --user --prefix=$HOME Setup.lhs: /usr/local/lib/ghc-6.10.1/directory-1.0.0.2/HSdirectory-1.0.0.2.o: unknown symbol `unixzm2zi3zi1zi0_SystemziPosixziDirectory_a12_info' Setup.lhs: Setup.lhs: unable to load package `directory-1.0.0.2' --- Here's my ghc version: drc@tangerine:~/local/haskell/xmonad$ ghc --version The Glorious Glasgow Haskell Compilation System, version 6.10.1 --- Here's what I have installed: drc@tangerine:~/local/haskell/xmonad$ ghc-pkg list /usr/local/lib/ghc-6.10.1/./package.conf: Cabal-1.6.0.1, array-0.2.0.0, base-3.0.3.0, base-4.0.0.0, bytestring-0.9.1.4, containers-0.2.0.0, directory-1.0.0.2, editline-0.2.1.0, filepath-1.1.0.1, (ghc-6.10.1), ghc-prim-0.1.0.0, haddock-2.3.0, haskell98-1.0.1.0, hpc-0.5.0.2, integer-0.1.0.0, old-locale-1.0.0.1, old-time-1.0.0.1, packedstring-0.1.0.1, pretty-1.0.1.0, process-1.0.1.0, random-1.0.0.1, rts-1.0, syb-0.1.0.0, template-haskell-2.3.0.0, unix-2.3.1.0 /home/drc/.ghc/i386-linux-6.10.1/package.conf: Cabal-1.6.0.1, HTTP-3001.1.5, HTTP-4000.0.4, X11-1.4.5, X11-xft-0.3, ghc-paths-0.1.0.5, haddock-2.4.1, haskell98-1.0.1.0, mtl-1.1.0.2, network-2.2.0.1, old-time-1.0.0.0, parsec-2.1.0.1, parsec-3.0.0, process-1.0.1.1, readline-1.0.1.0, unix-2.3.1.0, utf8-string-0.3.3, utf8-string-0.3.4, xmonad-0.8.1, xmonad-contrib-0.8.1, zlib-0.5.0.0 I'm running on a 32 bit machine, latest Ubuntu Intrepid. I'm not a Haskell programmer, just an enthusiastic Xmonad user. Any guidance would be much appreciated. I'd be happy to provide any information about my local setup that might prove useful. Oddly, I can build from source on my other machine, running 64 bit Ubuntu. Thank you, drc
