Recently gentoo switched to python 3.10 as default. But all available versions of sci-physics/lhapdf are only working with python 3.9 In order to solve this problems it's necessary to add lhapdf 6.5.2 which was released recently. Here is the "emerge --update --deep --newuse --ask @world" output: !! The ebuild selected to satisfy "sci-physics/lhapdf:0/0=" has unmet requirements. - sci-physics/lhapdf-6.3.0::gentoo USE="-doc -examples -python" ABI_X86="(64)" PYTHON_TARGETS="-python3_8 -python3_9" The following REQUIRED_USE flag constraints are unsatisfied: any-of ( python_targets_python3_8 python_targets_python3_9 ) The above constraints are a subset of the following complete expression: python? ( any-of ( python_targets_python3_8 python_targets_python3_9 ) ) any-of ( python_targets_python3_8 python_targets_python3_9 ) (dependency required by "sci-physics/pythia-8.2.45::gentoo" [installed]) (dependency required by "sci-physics/root-6.26.04::gentoo[pythia8]" [ebuild]) (dependency required by "@selected" [set]) (dependency required by "@world" [argument]) Reproducible: Always
