Because it's not linking with the library, it's copying it (along with
many other non-library-like files) into an appliance.

It depends on fixed paths because fixed paths are used to build the
appliance.  Therefore the dependencies tell us when something isn't
going to work at runtime, instead of having the package silently
broken by changes such as the one discussed in the OP.

Now you may think that this is a bad way to build an appliance, but no
one has come up with any better ideas for that so far.
