IE9 JavaScript error: toplevel constant JSON referenced by Watir::Object::JSON

[ematta]

When I run browser.performance (browser being my Watir::Browser object) I get the following error:

c:/Ruby200/lib/ruby/gems/2.0.0/gems/watir-webdriver-performance-0.2.2/lib/watir-webdriver-performance.rb:91: warning: toplevel constant JSON referenced by Watir
::Object::JSON

Running:

IE9 9.0.8112.16421 on Windows 7 machine (OS is 64 bit, IE is 32 bit)

ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

Are there any updates for this issue? I am seeing the same Selenium::WebDriver::Error::JavascriptError: JavaScript error in IE8.

[dnldpavlik]

I was running into this issue, ended up have it resolved when I added

require 'json'
