sboinstall error - brave-browser installation - slackware 14.2 stable

This is the error I get with sboinstall when install brave-browser in slackware 14.2 stable:

"/opt/brave.com/brave/brave: error while loading shared libraries: libxkbcommon.so.0: cannot open shared object file: No such file or directory"

P.S. I couldn't log into git and write to 'pink-mist'

thanks,
