Subject: Re: error "copyplist failed with exit code 127"

Could the problem be related to these posts?

Those have exit code 71 instead of 127, so I don't know if it's the
same thing. I'm also not quite sure if the problem is with Rubys
installed as /usr/bin/ruby, or if other versions in the path cause it
too.
