Can't connect

[dmjio]

Sorry, I'm haskell noob. But I can't connect in ghci.

The function connect' is applied to two arguments, │ ] but its typeHost -> IOE Pipe' has only one │}
In a stmt of an interactive GHCi command: │
con <- connect "127.0.0.1" []

Any ideas? Mongo is running... looks like a type error
