I guess that means I really need to link statically, right?
not neccesarily - you *can* bundle all libs and executable together into an installer (this is a good read for you: http://doc.qt.nokia.com/4.7/deployment.html)
but... your target architecture needs to be compatible with the produced executable. This doesn't seem to be the case in your example: 32bit target trying to run 64bit executable
This will not work regardless of whether you build the app dynamic or static.
