The package is split into a few independent subpackages. libini_config.so has internal dependencies (libcollection.so and libbasicobjects.so) that it would have to pull as dependency systematically. Those libraries don't seem to have any use outside of this project so they are bundled together for now. If it turns out that a split is required, it can be safely done in the future (libini_config.so, which is installed, would pull those requirements).
