Unfortunately cabal-dev ghci does not work in this project, i get an error:
Loading package download-0.3.2 ... linking ... ghc: /home/stulli/haskell/ifdl/cabal-
The cabal-dev setup doesn't work very well for ghci, so it might very well be that it also doesn't work well for runhaskell. Maybe virthualenv will work better for this use case?
cabal-dev
ghci
