I think it won't be considered derived work if you simply include the Meteor library as a separate script tag. But I don't think Meteor separates out their library code from your Meteor client side code. In addition, if you minify the concatenation of Meteor code with all your other client side js libraries, then I believe that will trigger the derived work provision.
