The fileutils.rb is a standard file found in the RubyStdLib subfolder within the SketchUp Tools.
It does not auto-load when SketchUp starts, BUT can be required thus:
require "fileutils.rb"
Since the path to the RubyStdLib subfolder should be auto-added to the $: the .rb should be found in that folder.
Obviously something is failing...

Check a few things...
Is the RubyStdLib subfolder within the SketchUp Tools ?
Does it contain a file named fileutils.rb ?
If not reinstall SketchUp v2014 [latest version]...
Is the path to RubyStdLib included in the $: ? To check that you just type $: in the Ruby Console...
If you type require "fileutils.rb" in the Ruby Console what is the result ?

Report back...

Is the RubyStdLib subfolder within the SketchUp Tools ?yes

Does it contain a file named fileutils.rb ? yes

If not reinstall SketchUp v2014 [latest version]... 14.0.49

Is the path to RubyStdLib included in the $: ? To check that you just type $: in the Ruby Console... i don't think so

If you type require "fileutils.rb" in the Ruby Console what is the result ? false

trying to install this extension on my SU2014 but cannot find this on my toolbar, and every time i restart SU, it shows:
