This is due to the fact that gitit uses cabal's "data-files" section to make data files available at runtime. These are installed in the path mentioned in the error on the machine where you built, so they will be missing on the machine where you copied the binary. This was the reason we stopped using data-files, but obviously that won't work for you. I've looked briefly into getting stack to write these data files to a different (relative?) path so you could copy them over with the executable, but was unable to find anything. Maybe someone else with more stack knowledge can chime in on that?
