Just noted missing RoR info on the Dreamhost wiki. Dreamhost say it was user generated and can't help. If anyone knows how to fix this up/has the info I'd be very interested. Here's the details below:
Unfortunately, I don't have that information. That wiki article was
completely created by our customers, so we don't have any alternate links
for that broken one. Sorry about that. You might want to try searching
Google to see if you can find more info about it. Let us know if you have
any further questions.
