After a lot of struggling I finally managed to install the packages network and ftpsh on a Windows machine. After installing msys and adjusting the path for mingW, the command "cabal install network" finally worked. At least I thought it was. But when I put "import Network.FTP.Client" in myprogram.hs, GHC can't find the package. After a while I found how to get more info: ghc --make -v myprogram.hs -package ftphs. There was a long list of warnings, missing packages, wrong versionnumbers... arghh... Ghc also complained about shadowed packages. i.e. When I do: ghc-dpg list, I get 2 versions of Win32-2.2.0.2. They have equal version numbers but the package-id's are different. One package is stored in \program files\Haskell Platform/2010.2.0.0/lib/package.conf.d and the other is stored at \Docs&Settings\Kees\Application Data\ghc\i386-mingw32-6.12.3\package.conf.d The packages from Docs&Settings map were creates using msys. The other were create before installing network, ftpsh etc (normal cmd command line). I wonder whether the 2 directories are okay and if not, how do I change the cabal-directory for msys/mingw? As a beginner I love the language. Using Haskell as a platform (at least for Win32 development) with all it's version dependencies is in my opinion difficult (compared to Java, C#, Delphi). Can somebody help? Kees
