Hi Andreas,
You are right. The way you integrate the libraries in your code is not the way that will work for HANA XS projects. This is why it doesn't accept the queue function (library is not loaded) and also why the 3.x only D3JS funcitons are not accepted (only the internal D3JS library is loading and these functions were not a part of 2.9 yet).
To integrate third party libraries, you need to add XSJSLIB files to your project. These need to pass the server-side JSLint checks before accepted by the XS engine. (Client-side checks that fail might not count though).
Please see this post from David Brookler for more information.
