Unable to run tests for acts_as_nested_set

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”

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.
