Doing a ⌃H document lookup in a Ruby on Rails file won't lead me to the desired documentation. Instead, the lookup disambiguation menu loops infinitely.

This is, I assume, a problem with my Ruby installation, but it particularly bites me in TextMate, and I hope someone here can point me to a solution. I am running Ruby 1.8.6 (supplied with Leopard), Rails 1.2.6 (supplied with Leopard), ri 1.0.1 - 20041108, and TextMate 1.5.7 (1455). I am not aware of having installed any additional Ruby or Rails.

If I type "delete" in a Ruby on Rails document, and press ⌃H to look it up in the documentation, I find among the many choices "ActiveRecord::Base::delete". Selecting that does not produce the documentation window, but shows a second context menu containing:

ActiveRecord::Base::delete 1 ActiveRecord::Base::delete_all 2 ActiveRecord::Base::delete 3 ActiveRecord::Base::delete_all 4

Selecting one of these simply reopens the menu, and I'm stymied. I can't get my documentation.

"ri delete" on the command line produces a list in which every entry is duplicated. Refining to ActiveRecord::Base::delete shows ActiveRecord::Base::delete, ActiveRecord::Base::delete_all, ActiveRecord::Base::delete, ActiveRecord::Base::delete_all … and once again, I'm stymied. That's why I conclude it's a Ruby/ Rails installation problem. I'm not experienced enough to trace it.

Can anyone offer/point me to a fix?
