Re: [BUG] Recursive dependency when gnuplot added to org-babel-load-languages

[Donald Hunter <donald@sealgair.com>]

I hit the same bug when running emacs/master (5e940a353e37) and bisected
it to:

  commit 5a125fb5a9736bd3c67cf6ff9acc185d8e2260e2

      Update to Org 9.7.3

This is the org-mode commit that added (require 'ox-ascii)

      ob-gnuplot: Fix links and verbatim when converting tables

      * lisp/ob-gnuplot.el (org-babel-gnuplot-table-to-data): Use custom
      backend to export table data.  The backend will export links verbatim,
      without trying to resolve them and drop verbatim markers from data
      fields.

To reproduce the issue, run emacs -q then eval:

(custom-set-variables
 '(org-babel-load-languages
   '((gnuplot . t) (emacs-lisp . t))))

and start org-mode.

This fixes it for me:
