Created attachment 455120 [details] build log Trying to re-merge dev-python/networkx-1.11 (not sure what part of my world update triggered this rebuild) I get an error building the documentation: atlas.py FAIL: This example needs Graphviz and either PyGraphviz or PyDotPlus circular_tree.py FAIL: This example needs Graphviz and either PyGraphviz or PyDotPlus Indeed, neither dev-python/pygraphviz nor dev-python/pydotplus is installed on my system. Nor is either of these listed as a dependency in the ebuild.
Those are optional dependencies, and are only pulled in with USE=examples. The docs build failed due to bug 594626.
