ISVs usually don't use package dependencies at all. They either link 
statically or ship the shared library as well.
Unless it is part of some kind of standard like LSB.

Let's explain it this way: no other communication method I can think of 
specifies the access library, but all the examples I can come up with specify 
the protocol instead: X11, DBUS, DCOP, Corba, IP, TCP/UDP, HTTP, etc
