I was wrong in thinking ${perl5.major} would be what ever the default of the perl5 portgroup was.

Shouldn't perl5.default_branch be a static version?
_resources/port1.0/group/perl5-1.0.tcl:
...
options perl5.default_branch perl5.branches
default perl5.branches {"5.8 5.10 5.12 5.14 5.16"}
default perl5.default_branch {[perl5_get_default_branch]}
proc perl5_get_default_branch {} {
    global prefix
    # use whatever ${prefix}/bin/perl5 was chosen, and if none, fall back to 5.12
    if {![catch {set val [lindex [split [exec ${prefix}/bin/perl5 -V:version] {'}] 1]}]} {
        return [join [lrange [split $val .] 0 1] .]
    } else {
        return 5.12
    }
}
...
default perl5.major {${perl5.default_branch}}
...
