This is not usually how so-versions are done.

The number on a shared lib most often signifies the API/ABI version.
That is ortogonal to the version of the lib itself.

This warning is given in the documentation for libtool (and I know
that boost does not use libtool):

   *_Never_* try to set the interface numbers so that they correspond
   to the release number of your package.  This is an abuse that only
   fosters misunderstanding of the purpose of library versions.
