So I'm guessing you're running some version of ruby under some version of
windows.

Well, do you have an X server? For example, are you running under cygwin?

It would be much more helpful if you could give the full context of where
you're running this.
* What O/S and version you're running under
* What ruby version you're running under, and where you got it from or
  how you installed it (e.g. one-click installer, which version?)
* What versions of relevant library/ies
