color-theme in emacs problem

[jindan]

I have just emerged color-theme 6.5.4, in emacs 21.3.1
when I put (require 'color-theme) in my .emacs, I got

color-theme-backup-original-values: Symbol's function definition is
void: color-theme-filter


detailed error with emacs --debug-init says:
Debugger entered--Lisp error: (wrong-type-argument keymapp nil)
define-key(nil [menu-bar Tools] ("Tools" keymap "Tools"))
byte-code("address@hidden
\"\"^Z仁^H\203(address@hidden@address@hidden@^HC\202*^$
easy-menu-get-map(nil ("Tools") nil)
easy-menu-add-item(nil ("Tools") "--")
byte-code("懒!\210旅呐#\210旅魄#\207" [require easymenu
