<p>I'm trying to use the <a href="http://optiflag.rubyforge.org/discussion.html" rel="nofollow noreferrer">Optiflag</a> package in my Ruby code and whenever I try to do the necessary <code>require optiflag.rb</code>, my program fails with the standard <code>no such file to load -- optiflag</code> message. I added the directory with that library to my $PATH variable, but it's still not working. Any ideas?</p>

is it a gem? Are you doing
```
```
require 'rubygems'
require 'optiflag'
```
```
or equivalent?
