It's dynamically linked [1] against Qt, so it will use the version of 
the library that is currently installed on the system. In this case, 
SMPlayer also reports that it's using Qt 4.5.3 in its about menu: "Using 
Qt 4.5.3 (compiled with Qt 4.5.2)". A rebuild of an application is 
required when one or more of the libraries it links against gets a 
"soname bump" which would indicate that its ABI [2] has changed.

Oh, and please use bottom-posting [3] when replying. :)
