superclass mismatch for class Annotation

Running with Rails 1.2.3, Ruby 1.8.6, rake 0.7.3 and rspec 1.0.8, I was getting the following error when running rake:

rake -T project_name
(in /home/apps/project_name)
rake aborted!
superclass mismatch for class Annotation

I solved the superclass mismatch error by removing the version number from the rspec directories in my Rails vendor/plugins directory:

cd vendor/plugins
ls -a 
-> rspec-1.0.8  rspec_on_rails-1.0.8

mv rspec-1.0.8 rspec
mv rspec_on_rails-1.0.8 rspec_on_rails

ls -a
-> rspec  rspec_on_rails

To ensure the correct rspec directory is set in the load path, regenerate the script/spec file by running:

ruby script/generate rspec

Great, now we can get back to development! ;-)
