Cool! Just got an email from DreamHost today:

Hey!

This is just a note to let you know that we’ve now completed the suggestion:

“Install all Ruby libraries and Ruby on Rails (including FastCGI extension).”

from the category “Software Installations”.

Ruby on Rails with FastCGI is now officially supported by DreamHost!

Very cool. Now I can start messing around with Rails, which I’ve heard a lot of good buzz about.
