Created attachment 354316 [details, diff] patch against Babel-1.2.ebuild Babel-1.2 seems to have moved the docs from doc/ to docs/ and they are no longer prebuilt. This makes it fail on dohtml in the install phase. I've attached an ebuild patch to build/install html docs (behind USE=doc), but I suppose now they could be built for man or other formats. I am not a python guy so feel free to pick this apart or rewrite completely.

Created attachment 354322 [details, diff] new ebuild patch idella4 pointed out that this doc build goes out and fetches some stuff via intersphinx_mapping, I've added a fix to prevent that. Used the same fix found in quite a few other python ebuilds.
Sorry about that. I've taken your patch, thanks!
