To explain: Binaries are generally linked against binaries, ie.
against a certain set of symbols only present in a certain build of a
binary; thus, usually libraries link against specific versionized
libraries.

If you update a library, binaries linked against the old version are
bound to stop working. In most unixoid systems, this is circumvented
(sometimes) by having the ability to have multiple libraries in
different versions installed [1](libgrandmascheesecake.so.1.0.0,
libgrandmascheesecake.so.1.1.2) and a symlink from the general name to
the recent one (libgrandmascheesecake.so ->
libgrandmascheesecake.so.1.1.2). However, usually you don't want to
have conflicting versions, so package management usually goes miles to
ensure that all packages in a certain distribution version are built
against the same library version.

Greetings,
Marcus


[1] windows-y systems usually ship all the libraries in the same
directory as the executable, which is --from a storage point of view--
quite like static linking.
