Textmate Backtracer 1.1 on RoR 1.1?

Has anyone got Textmate Backtracer to run on RoR 1.1?

I had a version (1.0 maybe?) running OK pre-RoR1.1, but now no such
luck. I downloaded textmate_backtracer-1.1.tgz, unzipped it and placed
it in ./vendor/plugins/ & restarted the server. When I trigger an error
in my app, the errors are not clickable.
