Sorry, I suppose my description was too synthetic. The problem is that ebuild for graph-tool-2.2.24 has unfeasible use flag dependency for ebuild graphviz. emerge: there are no ebuilds built with USE flags to satisfy "media-gfx/graphviz[python,python_targets_python2_7(-)?,-python_single_target_python2_7(-)]". Today I have correctly installed graph-tool-2.2.23 (after adding requested useflag +python to graphviz) since it use a simpler flag dependency media-gfx/graphviz[python] instead of media-gfx/graphviz[python,${PYTHON_USEDEP}] but I cannot still update it to 2.2.24 because of reported error (it only no more complain for missing +python flag since graphviz is now installed with it) # emerge -av graph-tool These are the packages that would be merged, in order: Calculating dependencies... done! emerge: there are no ebuilds built with USE flags to satisfy "media-gfx/graphviz[python,python_targets_python2_7(-)?,-python_single_target_python2_7(-)]". !!!

(In reply to Roberto Castagnola from comment #2) > The problem is that ebuild for graph-tool-2.2.24 has unfeasible use flag > dependency for ebuild graphviz. Sync up, the only versions in the tree now don't pull in graphviz and use cairo for graph rendering instead (graphviz support is deprecated upstream).
