You seem to be going about this the wrong way.  If you need to link
against 10.5 symbols, you can't perform a version check in main(),
because you'll still be linking against libraries that don't exist on
10.4 and below.

Why aren't you using the LSMinimumSystemVersion key in your
Info.plist?  Alternatively, you can use the "bootstrap" approach
documented here: http://weblog.bignerdranch.com/?p=13
