Created attachment 334408 [details] Build logs dev-python/sphinx-1.1.3-r3 fails to emerge with the USE=doc flag set; without the doc flag it partially succeeds, installing for Python 2.7 and failing for Python 3.2 Emerge information and build logs attached.
Both issues appear to relate to Jinja2 not being available for Python 3.2, looks like python-updater needs to be run. Please run 'emerge -1 jinja' and then try re-emerging sphinx.
The problem went away when I ran python-updater. It's the first time I've built a system using a slotted Python, and although everything was emerged with Python 2.x, apparently there was still confusion with Python 3.x
Indeed, whenever you get a new Python slot you need to run python-updater to ensure everything has a module built for the new version.
