it is probably a different (older) version of prototype; had they used 
the script loader, it would load the Wordpress-supplied prototype 
library and ignore the rest, and wouldn't break everything else; but 
then again, their plugin would not be guaranteed to work across 
Wordpress versions

this is a complicated problem, actually, because few libraries can 
accommodate several of their own versions running at the same time 
(actually, the only one I know is jQuery), and there is not much you can 
do, except for warning the users (or rewriting your javascripts for 
jQuery ;)).
