But I was not sure where to go with this. I am trying to add rspec  
testing to a “working” application and get the following error.

/Library/Ruby/Gems/1.8/gems/color-1.4.0/lib/color.rb:19: Color is not  
a module (TypeError)

I don’t really understand; I have not changed my environment except  
for recently updating all of my gems.

I apologize if this is the wrong group but any pointers would be  
appreciated.

I think you almost answered your own question… Looks like you  
updated the color gem and now it is conflicting with something else in  
your application that has Color defined.

I would start with a project wide search to find Color to see if there  
is something else that defines Color.
