Does cabal install --user or --prefix work on Windows at all? I tried: cabal install colour --user cabal install --user colour etc and all failed because install try to install at c:Program Files which I don't have permission writing. I have: cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library The Glorious Glasgow Haskell Compilation System, version 6.10.4 Thanks Jian ~ ~ ~ ~ ~ ~
