I originally sent this to the author listed in rubyforge, but maybe someone here has already dealt with this?
I was the original author of the plugin, however, ownership was given to Jonathan Viney over a year ago. He has been hosting it since that time and the rubyforge project page is dead, per the summary and news posted on the project page. anything submitted to the project page will never be seen. please see the readme for how to contact jonathan.

aha!
and the readme says
"For edge rails r7315 and above, use http://svn.viney.net.nz/things/branches/acts_as_modified_edge"
btw, the rubyforge page comes up pretty high in google
