I'm not sure exactly what you're trying to do.  When you say dynamically
require a file from within a class, do you mean something like this:

  class MyClass
    require 'something'
  end

When you say "mixin a method from this module", I think you mean "mixin
a module from this file" :-)

Finally, is it possible you really want to extend the current object,
rather than include it in the object's class?  Something like:

  class MyClass
    require 'something'    # contains SomeModule
    def my_method
      extend(SomeModule)
    end
  end

This would add the methods in SomeModule to the current object.
