py*-sphinx: execution of sphinx-build fails because of missing packages

[cjones051073 (Chris Jones)]

Sphinx 1.6.2 seems to rely on py*-typing as well as what would be called, maybe, py*-sphinx-contrib-websupport, except that this port does not yet exist.

Sphinx 1.6.2 moved websupport from a core submodule to an external one in sphinxcontrib. It is not part of the port py*-sphinx-contrib, and instead needs its own port; somehow.

primary issue appears to be

Similar issue with 10.9, only the "distribution not found" is sphinx-contrib. Log attached

log from 10.9

In the future, please Cc the port maintainers (port info --maintainers cmake).

[cjones051073 (Chris Jones)]

apologies. I thought this had become automatic in the move to GitHub..

[michaelld (Michael Dickens)]

Looks like the new Sphinx requires py*-typing, which is provided by MP but not a py*-sphinx dependency (at this time). I'm trying building with +docs to verify.

[michaelld (Michael Dickens)]

Yes, this is actually a Sphinx issue. If you execute "sphinx-build-2.7" alone, it errors out in the same way. Switching the title & adding in that port's maintainers.
