The Cabal package provides the library. The cabal-install package provides the 'cabal' command line tool. The deprecated package you're thinking of is cabal-get or cabal-setup. > > How do I install and configure it so that it is integrated best with > > GHC 6.10.1?

There is no need to put additional packages into the ghc install tree, indeed I would recommend against doing that. > Cabal wants to place package info in $HOME/.cabal.

If you want to do the build as user and just the install as root then you can use the --global --root-cmd=sudo options. If you want to use this every time then you can set that in the ~/.cabal/config file. > Well, there is the --global option but it is apparently only for registering > packages globally.

The cabal user guide lists the default install directories for global and user installs. The default ~/.cabal/config file is slightly self-documenting in that it lists the available options and their defaults: [..snip..] -- user-install: True [..snip..] install-dirs user -- prefix: /home/duncan/.cabal [..snip..] install-dirs global -- prefix: /usr/local [..snip..] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
