To do this for all files in a port's destroot directory whose names end with ".pl":


post-destroot {
    fs-traverse f ${destroot} {
        if {[file extension ${f}] eq ".pl"} {
            reinplace "s|^#!/usr/bin/perl|#!${prefix}/bin/perl${perl5.major}|" ${f}
        }
    }
}


(Assuming you have properly included the perl5 1.0 portgroup, or else manually set perl5.major to the right value.)
