Folks,

Anyone know of a Ruby library that defines random variables[1]?  I'd like
access to a variety of distributions.  I haven't seen anything like this
in Ruby.  Perhaps someone has, or can suggest a C library I might wrap.

Cheers,
Gavin

[1] By which I mean "an object that returns random numbers on request,
according to a configured distribution, bias, etc."  Sorry if my
terminology is wrong; the Wikipedia articles on the matter are making my
head spin.
