void variable exedir=

[houshuang]

I installed Emacs 24.4.90.2 with an empty .emacs.d (only the init.el from this tutorial), and installed haskell-mode. A lot of things work well, including opening a REPL, but when I try to get the type of an expression in the editor, it says "(void-variable exedir=)". However, I can't even find the variable exedir when searching through the Haskell-mode documentation, and opening the Haskell process buffer shows that the lookup actually takes place and works.

Sorry, but I don't really know what might be going on, I am not a haskell-mode developer myself.
My suggestion is to ask the question in the haskell-mode project instead https://github.com/haskell/haskell-mode

@houshuang Does the issue still persist?
