Caveat Emptor

By default, cabal installs to user's directory. This behavior can be toggle explicitly with --user or --global option. And this behavior must be consistend with

runhaskell Setup.hs configure

But unfortunately, this command defaults to use --global option implicitly. Thus only following two combos work

cabal install [--user] foo
runhaskell Setup.hs configure --user

sudo cabal install --global foo
runhaskell Setup.hs configure [--global]

Update Before First Time Use

cabal needs to pull down the package list. This can only be stored to user's directory ~/.cabal/

cabal update

List Instead of Search..

cabal calls it list... Perhaps it refers to ls |grep

cabal list foo
cabal list --installed
ghc-pkg list [--user|--global]

Uninstall

ghc-pkg unregister [--user|--global] [--force] foo

There is also a command called cabal-uninstall. Install and use it in this way

cabal-uninstall [--user|--global] foo
