restful_authentication

I had set up this plugin a week ago and it worked well for me, however
I had set it up just in a demo app. I had to install edge rails to
get it working. I figured since REST is (I believe) part of ege. Now
I installed it in my app with edge rails but from reading around
apparently there is some conflict with edge rails and the latest
engines build. So, now that I've probably confused everyone is there
a way for me to use the restful_authentication plugin without loading
edgerails ?

TIA
