What does class Random require?

Ruby
1

Simple question,

What does class Random require?
I tried this code:

r=Random.new(315)
printf("%d\n",r.rand(10))

and go this error:

test.rb:1: uninitialized constant Random (NameError)

spent some time looking in google and google groups but no luck.
It’s a pretty simple problem, maybe somebody here can help me?
TIA

If you can’t user Ruby 1.9.2, then maybe the simple-random gem will do
what you want (http://mendicantbug.com/2010/07/24/simple-random-number-
generator-gem/)

Alternatively, if you’re working in JRuby, you can just instantiate a
java.util.Random
