Problem
With the imminent upgrade in Dreamhost to Rails 2.1.1 (dreamhost blog post here), you may want to freeze your Rails version to a previous version, using capistrano.

Solution
On your local development pc freeze the rails:

rake rails:freeze:gems

Add the new code to your svn repository:

svn commit -m 'freeze rails'

And then deploy to dreamhost using capistrano:

cap deploy

Your rails project located on dreamhost should be frozen to your current Rails version.
