From use.desc: smp - Enable support for multiprocessors or multicore systems The fact that smp causes the unfortunate circle of pain tells us that it is one of the following packages, or their dependencies, is problematic: smp? ( >=dev-python/ipykernel-5.1.0[${PYTHON_USEDEP}] >=dev-python/ipyparallel-6.2.3[${PYTHON_USEDEP}] )" Do you currently have either of these packages installed ? * I don't use any of the involved packages, so I'm only guessing here. Perhaps someone with greater knowledge of Python on Gentoo could shed some light on this topic. It might be worth contacting MichaƂ (mgorny) if no one here can derive the source of this issue. -- Ashley Dixon suugaku.co.uk 2A9A 4117 DA96 D18A 8A7B B0D2 A30E BF25 F290 A8AA
