Clojure read-line function problem

I'm trying to get console input in my Clojure program, but when it gives me this error when it gets to that part of the program.

Exception in thread "main" java.lang.ClassCastException:
clojure.lang.LineNumberingPushbackReader cannot be cast to java.io.BufferedReader

the 'read' function works, but it's not what I need. Here is the code I'm using.

(defn prompt-read [prompt]
  (print (format "%s: " prompt))
  (flush )
  (read-line))

EDIT:

It is obviously just the version I'm using. It's the version included in the current sample code of Programming Clojure, I'll test out the current release version and see if that is the problem.

From stackoverflow

• Hmm, it seems to work for me. What version of Clojure are you using and how are you calling prompt-read? Here's what I'm getting back (here goo is my response):

  user=> (defn prompt-read [prompt]
  (print (format "%s: " prompt))
  (flush )
  (read-line))
  #'user/prompt-read
  user=> (prompt-read "foo")
  foo: goo
  "goo"
  

  Rayne : Yes sir that was the problem! Thanks!

  Chris Bunch : Of course. Clojure's been changing a lot lately so I've run into a lot of similar problems between the first beta of the book and the current beta (but apparently this will calm down a bit soon).

• The read-line problem was a known bug. It was fixed. Update your Clojure version.

  Rayne : I know, I was the one who reported that bug in the first place. I appreciate your enthusiasm but this answer was unnecessary.
