I am using this one: http://hackage.haskell.org/packages/archive/parsec/3.0.0/doc/html/Text-Parse... Is that version ok?
Ah ha - that's the later than the one I use. The authors must have decided to change its place in the modules hierarchy. In your case, you have already IO as part of the monad stack so you can write debug output to the console. This might produce a lot of output before a stack overflow though. A minor nit-pick - language pragmas generally go at the top of the file. It might even be that they _should_ go at the top of the file, I had to move it to make it run for me. Best wishes Stephen
