It looks to me that you gems aren't installed properly for your ruby 1.8.7 install, or you have gems installed that are not compatible with 1.8.7 and/or rails 2.3.4.

The error message is kinda obvious, isn't it?

in `gem_original_require': no such file to load -- aws/s3 (MissingSourceFile)

You don't have aws-s3 gem installed. Just install it:

gem install aws-s3

I'm pretty sure there will be other "missing" gems. Each ruby version in rvm has its own gem repository, so you have to reinstall all gems you need for ruby 1.8.7.

UPDATE: if you need earlier version of the gem (for example version 0.5.0):

gem install aws-s3 -v0.5

You have to require specific version of gem in rails, or it will automatically pick the latest version. Alternatively you can uninstall later version(s):

gem uninstall aws-s3
