Hello, I am a beginner in Haskell, and I am having a problem using cabal-install when I try to install the dependencies for a .cabal file. If I use <sudo cabal-install install package_name> I am able to install every package, one by one. When I installed cabal-install I had no problems and everything went on smoothly. These are the last lines when I installed it: [16 of 16] Compiling Main ( src/CabalInstall.hs, dist/build/cabal-install/cabal-install-tmp/Main.o ) Linking dist/build/cabal-install/cabal-install ... optimus:/usr/local/cabal-install_0 turingson$ sudo runghc Setup.lhs install Installing: /usr/local/lib/cabal-install-0.3.0/ghc-6.6 & /usr/local/bin cabal-install-0.3.0... optimus:/usr/local/cabal-install_0 turingson$ Here is the error I am getting when I try to use build-dep: optimus:/usr/local/hope turingson$ sudo cabal-install build-dep hope.cabal cabal-install: hope.cabal:9: Parse of field 'build-depends' failed: optimus:/usr/local/hope turingson$ That is the only error I am getting. Here is part of the content of the hope.cabal file: License-file: LICENSE Build-depends: base, network, mtl, parsec Do you know what I may be doing wrong or what can I do to work this around? Thanks, Adrian
