[Chicken-users] error configuring readline history for .csirc as per documentation

[Joe Python]

The link (http://wiki.call-cc.org/man/3/Using%20the%20interpreter#history-access) mentions the following procedure for using history with csi.

(use readline regex)
(current-input-port (make-gnu-readline-port))
(gnu-history-install-file-manager 
  (string-append (or (getenv "HOME") ".") "/.csi.history"))

However i get an error:

$ csi
