I've written the stub like so:

# This is just a stub that installs all REDUCE subports.
if {${name} eq ${subport}} {
    supported_archs noarch
    distfiles
    archive_sites

    use_configure   no

    build           {}

    depends_build-append\
        port:reduce-common\
        port:reduce-csl\
        port:reduce-psl\
        port:reduce-addons

    destroot {
        # Create a dummy file so the port can be successfully activated.
        xinstall -d ${docdir}
        set docfile [open ${docdir}/README.${name}.txt "w"]
        puts $docfile "REDUCE ${version} (MacPorts revision ${version}_${revision})\n"
        puts $docfile "${long_description}\n"
        close $docfile
        }
}

I don't think the order in which the subports are installed matters (I'm testing that presently). However an issue I've found is that if the install process is interrupted, a subsequent re-issue of 'port install reduce' will fail due to the fact that the subport that was interrupted isn't clean.
