dev-python/PyQt4 Each module is a separate library, and each has its own ABI that can change independently from the others. Downstream projects that rely only on PyQt4's python API are not affected by ABI changes, but those (very few) that link against one or more modules (e.g. kde-base/pykde4 I think) must be rebuilt.
