The dependencies are online. Your friend probably locked them, so you are unable to load them, since locked dependencies are only viewable to the publisher, not anyone else.
You have 2 solutions
1) Have your friend give you the dependencies, and put them in your Starcraft II/Mods folder, and then add them as the local version of the dependencies. You would go to File->Dependencies. Select each one, double click, then go to eh Local Files tab, and select the dependency file.
