Symbols function definition is void: oddp

[Logan Lee]

I get this error when M-x erc-select and entered server, username and password:
   Symbols function definition is void: oddp

My .emacs file is:
   ;; load paths
   (add-to-list 'load-path "/usr/share/emacs/site-lisp/erc")

   ;; erc
   (require 'erc)

And, I have confirmed the erc path is correct. I don't understand the error 
message in line 2 of this article.
