Require ob-calc, please don't use the snippet below.

judging from the error below, it looks as though you are still using the
old code (or the snippet below).  Please ensure you're on the latest and
give it another go.

in the latest code the line

  (list (math-read-number (calc-eval line)))

has been replaced by

  (list ((lambda (res)
    (if (numberp res) res (math-read-number res)))
   (calc-eval line)))
