Yes, it works if one install the toolchain directly in '/usr/local' as you said. // The problem here is it SEEMS the toolchain can only use the absolute path ' /usr/local/bin/repl_swift' to look for 'repl_swift', instead of a relative w.r.t the current path of 'swift' command. // The absolute-path-only case may bring extra works when one want to uninstall/reconfigure/upgrade the toolchian.
