Why does ldconfig insist on a trailing number?

I would imagine that the trailing number is the version number. If the
BerkeleyDB ports were taking full advantage of the versioning ability
supplied by ldconfig, they would have called their libraries libdb.so.2,
libdb.so.3 and libdb.so.4 instead of libdb2.so.0, libdb3.so.0, libdb4.so.0.
One might claim that the libraries need to be called different things due to
API changes, but generally, API changes happen on major number boundaries so
the verion number handles this.
