Gahh! how do you install the query_trace plugin?

Hello-

I am trying to install the query_trace plugin here:

I can’t figure out how to install it. I’ve tried script/install
plugin, I’ve tried svn, I’ve tried downloading the files and placing
them in the vendor/plugins directory, nothing seems to work. There’s
no install instructions. I appreciate any help. I’m using rails 2.02
btw.

thanks,
dino
