I think it's the fact that cabal-install by default does user-installs (now 
also on Windows, AFAIK), while the runhaskell ./Setup.hs way does global 
installs by default.

So your newly downloaded packages are in the user package-db (verify that 
via ghc-pkg list), and not available for global installs.

The fix would then be one of
a) use cabal-install to install scion (cd to scion directory and "cabal 
install" instead of runhaskell ...)
b) pass the "--user" flag to runhaskell ./Setup configure
c) reinstall the packages with the "--global" flag for cabal-install

IMO, a) is the best way.
