auctex doesn't work with xemacs 2.15-b19

The latest auctex cvs does not even load in xemacs 2.15-b19 (latest CVS 
version CVS-20050219). The error message produced is the following:

Error: An error has occurred while loading /Users/artemio/.xemacs/init.el:

Symbol's value as variable is void: @lispauctexdir@

Backtrace follows:

   (defvar TeX-lisp-directory @lispauctexdir@ "*The directory where most 
of the AUCTeX lisp files are located.\ntex-site.el (wherein this 
variable is defined) resides in its parent\ndirectory. For the location 
of lisp files associated with styles, see\nthe variables TeX-style-* 
(hand-generated lisp) and TeX-auto-*\n(automatically generated lisp).")
