This situation is custom practice for developpers and for
user's system. All applications can not be at the same level
of confidence relative to version released.
Extreme case are like the Red Hat rawhide, where header files
and libraries diverge not only on the minor release number but
also on the major release number.
Providing such capabilities allow developpers to release advance
version of the application for testing and reviewing.

The obligation of having only one version of a library
was causing slow adoption of new release of that library.
Or nightmare for administator, like polution of /usr/lib
I strongly beleived on tools like pkgconfig on which you can
query for availability of headers and library version and having
a directory where you can managed those packages configuration.
Thus, for linux system installation will have to compose with
another tool. And also for configuration.
