kimju-maemo-dev at inside.org did gyre and gimble:

 KJ> Yes I do. But they still don't help on picking the correct package. 

At least for one RPM-based distro (balcanization of RPM-based distros is
completely another topic) I know "apt-get install
libnautilus-extension.so.1" installed the proper package (as well as
"apt-get install /usr/bin/foobar").

And they should not to.

 KJ> For example: Program X uses libfoo, and libfoo had bug that this

It's a bug in packaging then. Such dependency won't be picked
automatically by dpkg-shlibdeps too, and need to be added manualy by
packager.
