Since there's no API/ABI convention for the sage library, you have to
rebuild giacpy_sage whenever the sage library is upgraded (because you
won't know if the upgrade broke what giacpy uses). So first, I would
change the SLOT="0" in the sage ebuild to SLOT="0/${PV}", so that the
subslot gets changed whenever the sage version changes.
Then in giacpy_sage, you depend on the subslot,
DEPEND="... >=sci-mathematics/sage-6.8:=[${PYTHON_USEDEP}] ..."
Whenever sage gets upgraded, its subslot changes, and giacpy_sage gets
rebuilt.
