Not a problem.

Thanks for trying it out. Interestingly, `guix graph --path` can’t find it, 
even with `-t bag`.

If you’d like to make a second try, some packages get the updated 
‘config.guess’ and ‘config.sub’ files from ‘automake’ instead (e.g., the 
‘indent’ package). I don’t know if there would be a cycle in that case as 
well or not.
