We have a PR in the works that should repair this issue. Till it's merged, I'd currently recommend the installation of lib32-yaml-cpp
from the AUR as a work around to this issue.
I'm also going to experiment with a few other ways to fix this. The main issue in all of this is when you have a yaml-cpp package installed the compiler will auto select that and we get this current issue. if you don't wish to install the extra package know there's a fix on the way. If you can, uninstall the yaml-cpp package and it'll use our submodule and work.
