Are you speaking of the mechanics on unix or of some other OS,
The mechanics of unix are simple:
Let application A be linked against a shared library with soname S.
At A's runtime, library /usr/lib/S is loaded. There is no "search for
the closest matching library".
Boost uses the convention that libfoo.so.X.Y.Z has SONAME
libfoo.so.X.Y.Z so the application always loads exactly the
library it was linked with. No heuristics.
