Hi,

I have compiled emacs 23.1 on ubuntu. And I am trying to color-theme
(6.6.0) from
http://www.nongnu.org/color-theme/#sec5

I have copied color-theme.el to ~/bin and have added these .emacs
; theme
(load-file "/home/hap/bin/color-theme.el")
(require 'color-theme)

But I get this error when i run emacs -debug-init:

͂Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  file-name-directory(nil)
  (concat (file-name-directory (locate-library "color-theme")) "/themes")

  eval((directory-files (concat (file-name-directory ...) "/themes") t

nil t)  ; Reading at buffer position 8867
  load-with-code-conversion("/home/hap/bin/color-theme.el"
"/home/hap/bin/color-theme.el" nil nil)

I have attached the color-theme.el.

Can you please tell me how can I fix my problem?

Thank you.
