Hi All,

When I include “gem ‘test-unit’” in my ruby file, it gives the following  
error. However my “gem list” does show test-unit. I am not sure what is  
missing when running the file as “ruby ci\_reporter.rb”. The actual ruby  
file is attached.

Installed the same in another machine, and it worked. Looks like the  
problem is due to installation of jruby. I have no clue of how they are  
related, but the problem is solved for now.

Some gems are special. Their name is not what you have to require.  
This is usually only the case with gems that contain a `-` in their  
name. Such as ‘test-unit’. When this happens you should consult  
the gem’s documentation. For example, you should require ‘test-unit’  
as ‘test/unit’.
