I recommend using distutils instead of Setup. I don't know whether it
already checks for timestamp dependencies between a shared object and
its libraries, but:

a) a patch to distutils performing such checks likely would be
   accepted, and
b) if distutils currently does such dependencies, you could easily
   override the build_ext command to perform the dependency check
   yourself.
