At least when the 'doc' flag is set, dev-python/sphinx will not build without dev-python/docutils: * Generation of documentation make -j3 'SPHINXBUILD=python2.7 ../sphinx-build.py' html python2.7 ../sphinx-build.py -b html -d _build/doctrees . _build/html Error: The Docutils library cannot be found. Did you install Sphinx and its dependencies correctly? make: *** [html] Error 1 emake failed * ERROR: dev-python/sphinx-1.0.7 failed (compile phase): * Generation of documentation failed After re-emerging dev-python/docutils, sphinx successfully installs. Please add this dependency so that revdep-rebuild can correctly compute the emerge sequence.
sphinx-1.0.7 already depends on docutils. It seems you got something broken going on in your system.
You probably forgot to run python-updater.
