Well, I'd reword that to “shared object dependencies are easy”.

Compiled code can have additional dependencies which might be optional
or required depending if it will gracefully fallback or degrade which
can be tricky to detect and which are not needed at build time, from
the top of my head those could be:

  * Programs being execve()ed.
  * Data files.
  * Unix sockets, named pipes.
  * System V/POSIX message queues, shared memory and semaphores.
  * D-BUS (or other IPC system) interfaces.
  * ...
