auctex and xsymbol related xemacs21 problem

[Micha Feigin <michf@math.tau.ac.il>]

I have xemacs21 installed with auctex and x-symbol installed.
x-symbol gave some error messages during instellation (I couldn't keep up,
if needed I can reinstall it)

I tried to add to .emacs these lines in order to make the packages work:
(require site-tex)
(x-symbol-initialize)

(require site-tex) causes a message to apear whenever opening a tex file:
file mode specification error: (error "cannot open doc string file
\"/usr/lib/xemacs-21.1-p2/i386-debian-linux/DOC\""
and I lost the highlighting, when I manually did:
M-x latex-mode
and turn font-lock on I got it back and the Latex menu (I also got the    
latex-math menu) (is this auctex?)

(x-symbol-initialize) returned an error message:
error in init file: symbol's function defenition is void:
x-symbol-initialize

Thanx
