Hi,

I have acts\_as\_nested\_set installed in my app under vendor/plugins.  
When I run ‘rake test:plugins’ I get the following error:

/usr/bin/ruby1.8 -Ilib:test “/var/lib/gems/1.8/gems/rake-0.8.1/lib/  
rake/rake\_test\_loader.rb” “vendor/plugins/acts\_as\_nested\_set/test/  
nested\_set\_test.rb”

rake aborted!  
Command failed with status (1): [/usr/bin/ruby1.8 -Ilib:test "/var/lib/

I am not sure if this is:

1. Something I am doing wrong
2. A problem with acts\_as\_nested\_set
3. A problem with rails plugins in general

I am running with a recent git version in vendor/rails, although the  
gem version of active support shows up in that trace for some reason.

Thanks in advance for any assistance.
