Hi, I am having trouble with rubyscript2exe when FileUtils is in my  
script. The error is easily reproducible:

require “FileUtils”  
puts “Hello World”

The error is:

ruby\>ruby rubyscript2exe.rb hello.rb --rubyscript2exe-verbose  
Tracing hello …  
Hello World  
Gathering files…

require ‘fileutils’ instead. Fixed the problem for me.

RubyScript2EXE does this:

require “fileutils”

If you require FileUtils in a different case, it gets required again by  
RubyScript2EXE, fileutils.rb gets loaded twice, which causes the  
problem.
