The source works just fine. The binaries don't. The new lib distros 
don't include the old lib, and vice versa. Often the missing lib isn't 
available. It's an ongoing nuisance.

It isn't like Windows, where the basic api's have been unchanged for 
nearly 20 years.

Mac OSX is the worst of the lot, there you get a "bus error" if you 
build for 10.5 and run it on 10.4.
