Yeah, I was trying to use some of the mathematics libraries for ruby, and found that we've got a lot of ports of things like NumPy that were created around 2006, and haven't been maintained - and there are multiple half-baked forks floating around trying to keep them running, and so the documentation is wrong. It's bad enough that I'm just going to switch to Python for this project.
