It's not the library, it's

runhaskell ./Setup.hs ...

versus

cabal install

The previous defaults to global installs, the latter to user installs.

So you can either

- run cabal install in the package directory (if you don't give a package 
name to install, it installs [tries to install] the package from the 
current directory)

- pass the --user flag to runhaskell ./Setup.hs,

runhaskell ./Setup.hs configure --user --prefix=C:\Users\Ralph\...

Getting into the habit of always using cabal install prevents such 
predicaments.
