Installation of xapian-binding for python3 fails.

[Gaurav Arora]

It seems like in configuration we check if sphinx.main function is present whereas sphinx doesn't have

sphinx.main for python3

Which seems to be failing the installation.

I checked while installing it on MacOS.

Need to reproduce for different system if it's a real issue. I was just helping someone install xapian so not sure if this is something they did wrong.

Seems like make is failing after that. Must be a issue with laptop.

I believe that the problem is that recent versions of sphinx have a different API, and we were relying perhaps on something a little too internal. Short term we could probably lock to an earlier version of sphinx, but it might be easier to figure out how to invoke it properly with more recent versions. (We'd then need to consider what the packaged versions are and whether we'd have to support both.)

Thanks for reporting, but this was actually already reported as #778. Closing this as a duplicate.
