If I checkout the acts\_as\_tree plugin from  
git://github.com/rails/acts\_as\_tree.git and try to run its unit tests, I  
get a failure:

$ rake  
(in /u/home/brian/git/acts\_as\_tree)  
/usr/local/bin/ruby -Ilib:lib  
“/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake\_test\_loader.rb”  
“test/acts\_as\_tree\_test.rb”  
/usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.2/lib/active\_support/dependencies.rb:276:in  
`load_missing_constant': uninitialized constant ActiveRecord::Acts (NameError) from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.2/lib/active_support/dependencies.rb:468:in`const\_missing’  
from ./test/…/init.rb:1  
… etc

However, I can make them run if I make a one-line addition to init.rb:

diff --git a/init.rb b/init.rb  
index 0901ddb…3e4d07b 100644  
— a/init.rb  
+++ b/init.rb  
@@ -1 +1,2 @@  
+require ‘active\_record/acts/tree’  
ActiveRecord::Base.send :include, ActiveRecord::Acts::Tree

Is there something odd about my environment, or is this an error in the  
plugin? I have rails 2.1.2 and rake 0.8.3 gems installed, but I’m  
testing acts\_as\_tree separately, not within a rails project.

Thanks,
