World of Confusion

[b1g1d3a]

Can someone who has successfully built this software on Arch PM or respond to this post? 

I humbly submit that I perceive the general linux build instructions to be incorrect:

* There is no 'build-source-libs.sh'
$ find . -name "build-source-libs.sh
$

* following the README buried within 'libraries/source/spidermonkey', "... just run build.sh," you get
`ModuleNotFoundError: No module named 'six.moves'`

* buried in this forum and somewhere on the issue tracker which is a nightmare to navigate (constant error popups), there is a reference to a patch for the above, but the branch does not seem to exist in git.
git switch py312
fatal: invalid reference: py312

Sorry, but this project is not worth a darn to me if we use git but do not bother with parity between SVN and git, so I remain at the point where I throw up my hands in defeat. Please help, so I can help.
