Hey i got an White Macbook and, has to go in 10 hours to a conference. And I'm having a lot of problems.

First, I wanted to have Rails 3, so I used MacPorts to install Ruby 1.8.7. Tt worked well ;) So now I was thinking I should install Rails 3.. but no, no!.. it says..

$ sudo gem install rails --pre

ERROR: Error installing rails:

activesupport requires Ruby version >= 1.8.7.

So what can I do? I have 1.8.7 !
