I've tried this but cannot get it to execute my maxima code:

--8<---------------cut here---------------start------------->8---
    #+begin_src maxima
programmode: false;
eq: x**2-1 = 0;
solution: solve(eq, x);
print(solution);
    #+end_src
--8<---------------cut here---------------end--------------->8---

I get the following error:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (void-variable in-file)
  (format "maxima --very-quiet -r 'batchload(%S)$' %s" in-file cmdline)
  (let ((result-params (split-string (or (cdr (assoc :results params)) ""))) 
(cmdline (cdr (assoc :cmdline params))) (in-file (org-babel-temp-file 
"maxima-")) (cmd (format "maxima --very-quiet -r 'batchload(%S)$' %s" in-file 
cmdline))) (with-temp-file in-file (insert body)) (message cmd) ((lambda (raw) 
(delq nil (mapcar (lambda (line) (unless (or ... ... ...) line)) (split-string 
raw)))) (org-babel-eval cmd "")))

This was with a freshly invoked emacs (with my own ob-maxima.el moved
out of the way).

Any suggestions?

thanks,
