Comment (by cal@…):

 Oh, OK, that explains it. Non-root copies of MacPorts should be installed
 by following https://guide.macports.org/#installing.macports.source and
 passing `--with-no-root-privileges` switch to `./configure`, which will
 automatically set `install.user` to your user name.

 Note that running MacPorts without root privileges gives build systems
 unrestricted access to your home directory and your files. Running with
 `sudo` as root makes MacPorts drop privileges for builds to an
 unprivileged `macports` user.

 I think we can keep the variant, but add a code block that makes it the
 default if `install.user` is not `root`:
 {{{
 if {${install.user} ne "root"} {
   default_variants +homespool
 }
 }}}
