I have intalled EventMachine in JRuby (I am using Win32). When I try the server example, I get an error when 

```
require 'eventmachine'

```

The error is:

```
C:\dev\em>jruby server.rb

```

server.rb:1:in `require': no such file to load -- eventmachine (LoadError)
 from server.rb:1

But the gem is installed!

```
C:\dev\myapp>jruby -S gem install eventmachine
