Ok, I found the problem myself. Stupid mistake that I did not see since I mostly developed in Java so far. The problem was that I put the main method in the CommandLineInterface module into a class description called CommandLineInterface. Hence the linker could not find the definition of "main" in the CommandLIneInterfaceModule. The error had nothing to do with Tango. Sorry!
