This has been brought up before and we've rejected it. There is no reasonable way for rubygems to make sense of the values in requirements because their entirely system dependent.
In 2.0, gem metadata can be used to store these kinds of values for you to write a tool that will read them (which again will have to deal with the system dependent issues itself).
