Either run `cabal install catagory-extras` as your ordinary user account or if you really want to do a global install then do: {{{ sudo cabal install catagory-extras --global }}} or {{{ cabal install catagory-extras --global --root-cmd=sudo }}} The latter will do just the install part as root. Perhaps this is suprising and we should try and detect if we are root and if so then do a global install by default. Unfortunately detecting if we are running as root is not simple and not portable (and just because we are uid=0 does not mean we have permissions under modern unix security mechanims and likewise we can have permissions to do global installs without being a root user). -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/377#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
