In python_compile_all, if use doc, emake -C docs html_noapi is called. docs/Makefile calls autogen_config.py, which wants to from ipykernel.kernelapp import IPKernelApp So, the long list in DEPEND doc? ( ... ) must also include dev-python/ipykernel[${PYTHON_USEDEP}]
*** Bug 622794 has been marked as a duplicate of this bug. ***
Old bug, but as of today, ipykernel is in ipython's doc? deps.
