I used to be able to install plugins, but for some reason the plugins  
system has stopped working for me.

If I try to install something like comatose, I get the following:

C:\rails\BAct\>ruby script/plugin source  
[http://mattmccray.com/svn/rails/plugins](http://mattmccray.com/svn/rails/plugins)  
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active\_support/dependencies.rb:422:in  
`remove_const': cannot remove Object::OPT_TABLE (NameError) from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:422:in `send’  
from

`remove_constant' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:368:in `new\_constants\_in’  
from

`each' from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:368:in `new\_constants\_in’  
from  
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active\_support/dependencies.rb:495:in  
`require’  
from script/plugin:3

I get the same set of errors (exactly) for almost any plugins command I  
try.

I am using Windows XP, rails 1.2.3, and have updated all of my gems.

Anybody know what I am doing wrong, or how to fix this?
