If the files aren't in standard library locations, you'll want to make sure that you name them relative to the source file using something like:

require File.join(File.expand_path(File.dirname(__FILE__)), 'otherfile')

This ensures that the require method sees a fully qualified path to 'otherfile' where 'otherfile' is found relative to the directory containing the source file instead of relative to the current working directory of the process.
