Comment (by mtb19@…):

 Shouldn't it avoid using root:wheel explicitly in a local (non-root) user
 install of MacPorts (e.g., with ... --with-no-root-privileges --with-
 install-user="$(id -n -u)" --with-install-group="$(id -n -g)" ... )? As
 far as I can see, there's no setuid, so root:wheel doesn't appear
 necessary. I might have missed something?
