As Andrea (and the README file) say you need to
ghc --make Setup
./Setup configure --user
The reason the first thing you tried did not work is due to:
#325 SHGetFolderPath requiered to configure cabal on windows
The solution is for some Windows person to update the Win32 binding
package to bind these functions, then we can import them directly rather
than having to FFI import them ourselves (which does not work in ghci
because we cannot tell ghci which extra dll libs are needed).
