version control autoload, key bindings missing

Hello, In XEmacs 21.0 "Pyrenean63" [Lucid] (i586-pc-linux) of Sun Feb 28 1999 on viisa.dna.fi - I made changes in a file that is under version control. - I try to type C-x v v to make a check in (that worked in xemacs 20.4). - Xemacs complains about unbound key C-x v (that is, even the prefix is undefined). - I type: M-x vc-next-action, it does the check in. - My packages are installed from xemacs-sumo-1999-02-02.tar.gz. I looked into .../vc/vc.el, and into ...dired/dired.el (dired is a package that works), and I noticed that the vc/auto-autoloads.el surely defines the vc-* functions but they are not bound to any keys (as dired functions are in dired/auto-autoloads.el). Here I give up, because I am not sure if I am on right track. Recent keystrokes: C-x C-f r o o t s / t a k a l a RET SPC BS C-x v m isc-user Recent messages (most recent first): Parsing /home/juha/.mailrc... Loading mail-abbrevs...done Loading mail-abbrevs...
