Use mit-scheme instead of guile for org-mode code block evaluation

Question

I have a code block in org mode:

#+BEGIN_SRC scheme
  (define (even? n)
    (= (remainder n 2) 0))

  (even? 3)
#+END_SRC

When I do C-c C-c to evaluate the code, I get the error '/bin/bash: guile: command not found'

I guess this is because org-babel expects that the scheme implementation installed is guile, but I have mit-scheme which I can run from the command line just by calling 'scheme'.

How do I get org-babel to use mit-scheme instead of trying to use guile?

This similar question doesn't solve my issue as the answer is very specific to racket.

Answer 1

Try to change the geiser-default-implementation variable - that's used by ob-scheme package to evaluate Scheme code blocks...
