My install of MOS on Arch Linux (Manjaro) failed

I am following the install instructions given in documentation for Arch Linux.

I got past the error with the path given for “cd”… cd mos-tool/mos/archlinux_pkgbuild/mos-release

I found makepkg in a cli folder (trust this the right one)
home/<>/mos/cli/archlinux_pkgbuild/mos-release

Had to install a few dependencies.

Then got this error message during install routine (lots of fetches etc.):

(this is the last fetch shown)

fetch “gopkg.in/yaml.v2”
make: Nothing to be done for ‘build’.
==> Entering fakeroot environment…
==> Starting package()…
install: cannot stat ‘/home/<>/mos/cli/archlinux_pkgbuild/mos-release/src/go/src/github.com/mongoose-os/mos/mos/mos’: No such file or directory
==> ERROR: A failure occurred in package().
Aborting…

How do I fix this “No such file or directory”

Thanks
