Funny you mention that because you do not include SDL (and rightfully so because the actual configuration for SDL can differ from system to system) and i actually had to remove SDL from some older games to get them to work under Linux exactly because they decided to ship the libs they relied on (and SDL wasn't the only problematic one, just the most known). Shipping libraries only helps if whatever these libraries rely on is also stable and the functionality they provide is still available. After all a library might still be using a stable ABI so all it can tell you is that OSS is not supported - which while technically correct and wont cause the program to crash (assuming it can handle not having sound) isn't very useful in practice.
