Though I'm not sure what your goal is, how about:

(1) ignore that warning. 
(2) do testing in different namespaces if it is possible. 
(3) use Module#remove_const: 

      class C
        MOD_RUBY = true
        remove_const :MOD_RUBY
        MOD_RUBY = false
      end

(4) use a class variable instead of a constant in the product. 


Hope this helps,
