Dreamhost launch issues. What gems are used in my rails app?

Hi guys,

I made a quick app for a family member to be deployed on Dreamhost (low budget). It's my first time deploying on DH so I'm not familiar with the restrictions.

I'm having an issue where I've been able to get git on both systems and used capistrano to deploy the app. However migrations fail. I also tried exporting my local staging mysql schema and importing it on the DH mysql database for production (same schema) and the site still fails to load.

The only thing I can think of at the moment is that it is a gem issue. I haven't used any gems knowingly, I've only used plugins (authlogic, enum-column, paperclip, searchlogic, and will_paginate). However, some of these may use plugins (may) use gems. Anyone know of a way to get this info easily?

OR.. maybe it has nothing to do with gems?? Here is the passenger error page just in case, Any help is appreciated!!:

Have you tried to run

rake gems:install

on the server to install all required gems?

Did you see this? What is at line 9 in environment.rb?

Yea tried that - there was nothing to install. I think I just figured out what's partly wrong. I had to install rails 2.3.3 on DH. Now I'm getting a different error.

Thanks!

for migrations, have you tried running rake db:migrate RAILS_ENV=production ? That may or may not work. As far as the plugins go, you shouldnt need gems to make them work, or if you did you would only get an error when trying to use them. I believe paperclip does require ImageMagick though. You can see your gems if you type gem list --local in your terminal. If you contact Dreamhost they'll probably be able to tell you more too.
