No, weak linking doesn't do that.
You want deferred binding: if the symbol you want is not present at load time but appears later, resolve to that one at that time. dlopen+dlsym is the only way to get that on Mac OS.
Normal linking is required and not deferred: if the symbol you want is not present at load time, your process halts.
Weak linking is optional, but still not deferred: if the symbol you want is not present at load time, then your references resolve to NULL. You don't get a chance to try again later.
