That's some stupid Flex Builder error that usually says that you have some other error in your application and sometimes - that you have no errors at all. Clean you project (Project menu -> Clean) and it should be gone.

You'll get this error if the given code is part of an <mx:Script></mx:Script> tag in an mxml file. That can happen when you use the <mx:Script source="filename.as"/> method to include ActionScript to your mxml components. If that is the case here, you can fix it by deleting the package block.

_{I'd rather copy the code into the CDATA block inside the <mx:Script> tag than keeping it in a separate file, but that's your choice.}
