PovRay Mode will not work??

[Christian Herenz]

Hi,
I want do create some PovRay Files with emacs, so I found a major mode
for it:
http://www.acc.umu.se/~woormie/povray/
It will not work :(
I always get the error (when M-x pov-mode)
"Symbol's value as variable is void: data-directory-list", I also get
that, when I eval the buffer with pov-mode.el :(
What is wrong here? Maybe tthis mode is incompatible with emacs 22.1.1 ??
Do you know other modes for editing POV files?
Greetz,
Christian
