1) Use GNU libtool to build shared libraries on non-FreeBSD
systems (or on FreeBSD systems when using ports). 2) Overhaul the versioning logic. In particular, SHLIB_MAJOR number is now computed as "major+minor", which ensures library versions are the same for the FreeBSD build system and the portable libtool/autoconf/automake build system.
