Kernel#require_relative を使えということでしょうね。

------------------------------------ Kernel#require_relative
     require_relative(path)
------------------------------------------------------------
     require_relative complements the builtin method 
     require by allowing you to load a file that is 
     relative to the file containing the require_relative 
     statement.

     When you use require to load a file, you are usually 
     accessing functionality that has been properly 
     installed, and made accessible, in your system. 
     require does not offer a good solution for loading 
     files within the project's code. This may be useful 
     during a development phase, for accessing test data, 
     or even for accessing files that are "locked" away 
     inside a project, not intended for outside use.

     For example, if you have unit test classes in the 
     "test" directory, and data for them under the test 
     "test/data" directory, then you might use a line like 
     this in a test case:

       require_relative "data/customer_data_1"

     Since neither "test" nor "test/data" are likely to be 
     in Ruby's library path (and for good reason), a normal 
     require won't find them. require_relative is a good 
     solution for this particular problem.

     You may include or omit the extension (.rb or .so) of 
     the file you are loading.

     path must respond to to_str.
