Whenever I try to install a plugin I get the following error:

e:/apps/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.1/lib/  
active\_support/dependencies.rb:422:in `remove_const': cannot remove Object::OPT_TABLE (NameError) from e:/apps/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.1/ lib/active_support/dependencies.rb:422:in`send’

```
    from script/plugin:3

```

I would be grateful if somebody could shed some light.  
Thanks
