True enough, but there's nothing in OSXs .dmg spec (or Whatever.app,
more precisely) that helps with dependencies - either the README says
'install libfoo first' or libfoo is bundled with the application.

As far as OSX goes, 'the package manager' == 'the user'. Software update
makes no attempt to monitor 3rd party apps, and gives users a false sense
of security. This is one area where even RPM is an improvement on OSX/windows.

Libc6 depends closely on the kernel. It's not something you want
to give a custom copy of to each app.
Although some of the 'each app has its own library' issues are addressed 
in netbsds pkgviews framework, have a google.
