Can activesupport gem be used in "standalone" fashion?


i’m using ruby 1.8.2, rubygem 0.8.10, rails 1.0.0 where activesupport
version = 1.2.5

when i try to run this in RADRail, i get a NoMethodError:

require ‘rubygems’
require_gem “activesupport”

print + 2.days

the error message is: c:/e312workspace/first/test3.rb:5: undefined
method `days’ for 2:Fixnum (NoMethodError)

is there a way to use the numeric/time core_ext in a plain ruby app? if
so, how?
thanks for any help!
