Required feature ‘scheme’ was not provided (scheme REPL in emacs)

It's probably very easy but I simply can't get a running scheme REPL in emacs.

First I installed MIT scheme and added
(setq scheme-program-name "my/path/to/bin/mit-scheme.exe")
to my init.el. But when I typed M-x run-scheme RET I got the error Required feature ‘scheme’ was not provided

So I installed quack and added (require 'quack) to my init.el Now when I start emacs I get the same error:Required feature ‘scheme’ was not provided

Am I missing a step?

Update

Maybe it simply doesn't work under windows:

Running Scheme under gnu-emacs If you want to run Scheme as an inferior process in gnu-emacs or xemacs (again, this is not an option on Windows machines), then you'll need to:

Download the xscheme.elc file. This is a byte-compiled elisp file that tells emacs how to run and interact with MIT Scheme. (Source file

is xscheme.el in case you're interested.)

This file should replace the xscheme.elc file that comes with emacs. You'll have to find the appropriate directory on your system.

On my Mandrake Linux system, this is the directory: /usr/share/emacs/21.3/lisp. (This step is not necessary if you are running MIT/GNU Scheme from the CS department machines.)

Add the following line to your ~/.emacs file

(load-library "xscheme")

Following doesn't work either

Quick Setup

Here is the short list of instruction's for those of you who want to get started in a hurry. An explanation of each step follows below.

  1. Open up emacs (or any other editor) in you home directory.
  2. Open up the file ".emacs" and add the following line: (set-variable (quote scheme-program-name) "stk")
  3. Save the file. You only need to do steps 1-3 once. If you were editing the file in Emacs, restart Emacs.
  4. Start up Emacs and type the following sequence of keys: M-x run-scheme A new buffer will open up with stk started inside of it.

The error "required feature scheme was not provided" means that the first "scheme.el" found in your load-path does not contain a provide statement. Either your Emacs installation is broken (unlikely), or (more likely) you've installed some random scheme.el that hides the default one. Find it and remove it. Eg try M-x list-load-path-shadows.
