Configure fails with SpiderMonkey error

[MirceaKitsune]

Hello. I'm experiencing a compilation issue for latest 0 A.D. Git on latest Manjaro Linux stable, would like to know when a fix is projected. I tried asking on Discord but some bot called MEE6 glitched out DM'd me an unrelated spam warning and this morning my mention of the issue was removed from the server, no idea what must have happened but hopefully it's okay to post here. Here's the relevant part of the log, the complaint seems to be about something called SpiderMonkey and a module named six.moves:

There is a fix but there is little activity so i don't think it will be commited soon.

Ah, it's a Python version issue? I hope at least an emergency fix like this is possible to address soon, especially if a PR exists and only needs approval. I have the 0 A.D. release installed by the package manager, but it's already well behind the many changes and features in Git so I've only used the later for a long while.

The problem is that the fix is very involved so it's acceptance will take a while. Do note you can apply the patch without waiting for it to be merged though

Or, you can install an older version of python3, such as v3.11, and build with that.
