*Lots* of libraries have compile-time options that can result in
binary incompatibility. And yet somehow, binary package distributions
for Linux systems manage not only to be usable, but *very* useful to
The issues you mention are real, and it is important to be mindful of
them. But you overstate their effect. The conclusion that these
circumstances mean, "By far the best way to manage boost is to
distribute it as 'part of' your application," is fallacy. The millions
of happy hapless binary Linux distribution users are testament to that.
