Well, as I said, the prebuilt framework in the developer package is 
already linked as such.  You have to build a custom library in order to 
get that behavior.  The "versioning stuff" is a couple extra 
directories and a few symlinks, so that's really a non-issue.  
Including the headers by default isn't something to worry about either, 
they're not terribly big, they compress awfully well, and they're 
trivial to strip if you really want to take them out.

Frameworks have additional advantages, but SDL doesn't use any of them. 
  For example, SDL could include resources (nibs or plugins for example) 
and reference them relatively to the framework.  You can't do that 
(usefully) with a bare dylib.

I recommend frameworks because it's the easiest way to do it correctly.
