I don't think you can use D.eval in the way you are trying to. After reading the documentation, there are a few things you need to do...
Instantiate an object of the type you are trying to use. You don't need to use this object but it needs to be created so Flex adds the class to the SWC. For example... import mx.controls.Label; var xxx:Label = new Label(); To crate a new Label (I think) you would have to do it this way... var prog:String = 'import mx.controls.Label;\n' + 'new Label()'; var myLabel:Label = D.eval(prog) as Label; You will probably need to contact the developers of D.eval for further support. This API seems very specialized and, it seems, you are the only one using it (Other than the developer).
