There seems to be an issue when running Rails 1.0 and the latest trunk  
version of Engines itself. If I gather correctly this version should be  
compatible with both 1.0 as well as EDGE/1.1. It happens in the file:  
dependencies\_extensions.rb.

As it happens, now I’m getting Stack Level too Deep errors using Edge  
Rails + svn trunk of Engines plugin.

Ouch…

Have you followed the instructions in the README file / on the website  
regarding Edge Rails and Engines?

[http://rails-engines.org/wiki/pages/Using+Engines+with+Edge+Rails](http://rails-engines.org/wiki/pages/Using+Engines+with+Edge+Rails)

Basically, it sounds like the engines plugin is trying to use the  
‘old’ dependency loading mechanism.
