Unless it has changed recently, on OSX .dylibs are dynamically loadable,
but not *un*loadable, because dynamically loading shared libraries was a
bit of a hack on top of Mach-O.  Support for loading -- rather than
linking -- dylibs was originally a 3rd-party library that Apple later
integrated, but it had limitations because of the way Mach-O works
internally.  Bundles are loadable /and/ unloadable but can't be linked
against.

HP-UX had similar issues with their particular brand of a.out as well
IIRC, but I am not sure of the current state of that platform.

All of my memories of this are from the OSX 10.3/10.4 timeframe, back
when we were first figuring out how to make dynamic loading play well
with KDE on OSX, so I may be getting some details wrong. :)
