Our apt-get, pkg, will not register shared library dependencies if the shared library does not have a soname. If the library gets changed and is no longer compatible with the previous version, and there is no soname to check, pkg will not know that all its dependencies need to be reinstalled. Hmpf. No mechanism for fallback / default soname? In that case you (or whoever acts as FreeBSD maintainer) may have to supply one.
