And there's also the option of linking statically at build time.

Please note I'm mentioning this only for completeness' sake, not
that I actually propose to descend to that ring of hell. (Except
for the few and far between well defined cases where this is
actually a reasonable thing to do.)

Static linking: 
    After shooting your foot you rebuild the world to recover.


Dynamic linking: 
    You shoot everyone's foot at once in a single shot.


Moral of the story: There is no silver bullet.
