Not only that, but on MacOSX for prebinding to occur all symbols have to 
be resolvable at link time, and even for linking in general unless you 
explicitly tell it otherwise (which libtool normally does, but there are 
cases in which it won't).

For the future portability, I implore that you go with what Bob 
suggested.  :)
