vc-svn.el problems...

Hey all,

I tried to play around with vc-svn today, and had some problems. Here's what
I did:

cp svn/tools/client-side/vc-svn.el ~/.elisp
add (load "vc-svn.el") to .emacs
load a versioned file into emacs.

First I got a message saying:
"Symbol's value as variable is void: vc-handled-backends"

I guessed that this might be due to the
"(add-to-list 'vc-handle-backends 'SVN)" on line 42 of vc-svn.el, so I tried
changing that to
(setq vc-handled-backends (list 'SVN))

while that silenced the error it didn't make vc-svn work :(

While I was editing vc-svn.el though, I noticed that several defcustom's
included :version "21.2.90.2" and so I checked my emacs version, which was
20.7.2.

Is the problem just that I need to update emacs, or is something else going
on?
