"Autoloading failed to define function haskell-interactive-bring" issue with running Haskell on Emacs

Following haskell repl in emacs, I could install packages. I used MELPA stable for repository ('("melpa-stable" . "http://stable.melpa.org/packages/") t))

I also installed the binaries with cabal.

Cabal version 1.22.6.0, GNU Emacs version 24.5.1 on Mac OS X 10.10.4.

The issue is that when I tried to run ghci with C-`, I have the error message. 

command-execute: Autoloading failed to define function haskell-interactive-bring

With C-c C-l, I have this error message. 

command-execute: Autoloading failed to define function haskell-process-load-or-reload

What might be wrong?

This is the Haskell related code in init.el.

(autoload 'ghc-init "ghc" nil t)
(autoload 'ghc-debug "ghc" nil t)

(custom-set-variables
 '(haskell-interactive-mode-hide-multi-line-errors nil)
 '(haskell-process-log t)
 '(haskell-process-type (quote cabal-repl)))

Added

In Emacs, auto completion shows that the "haskell-interactive-bring" function is available.

However, autoloading is failed.

The issue was that I have "haskell.el" that stores all the haskell related configuration setup. This has caused some conflict so that the "haskell.el" in the ELPA/haskell... package unable to properly loaded.

When I renamed my "haskell.el" to "haskell_config.el", everything seems to be working fine.
