Comment (by pixilla@…):

 cpan2port should remove duplicate dependencies:
 {{{
 $ cpan2port -t Net::Works
 ...
 $ grep moo perl/p5-net-works/Portfile
                     port:p5${perl5.major}-moo \
                     port:p5${perl5.major}-moo \
                     port:p5${perl5.major}-moo \
 }}}
