I'm sorry I missed that. Indeed, on the one "OS X" I ever tried to run
wget on, it didn't have wget.

Perhaps url-retrieve can be used instead. I have no time right now to
code it right, but here's a (synchronous) example with url + filetype +
filename all hardcoded :

(with-current-buffer
    (url-retrieve-synchronously
     "http://www.cnrtl.fr/images/css/bandeau.jpg";)
  (delete-region
   (point-min)
   (progn
     (re-search-forward "^$" nil 'move)
     (point)))
  (write-file
   (expand-file-name "~/tmp/foobar.jpg"))
  (pop-to-buffer
   (current-buffer)))

using url-retrieve (which is asynchroneous)  might also lift the
requirement on async.el
