Because the rest of the stack evolves and changes (compilers, shared
libraries, other packages), so you need to periodically (or, better
and more efficiently, each time a dependency changes) rebuild stuff to
check that it still works. Linux distributions have dedicated services
for this (see e.g. [1]).
