 > Thank you. Just a cosmetic patch: can you please take a look at the
 attached `git-perl-dependencies.diff​`?

 > If you use `depends_lib-append` instead of `depends_lib`, then you can
 omit the dependency on `port:perl${perl5.major}` which is already added by
 the `PortGroup`. And there is both `depends_run` and `depends_run-append`
 one after the other while they could be joined together. (I didn't sort
 the dependencies alphabetically to make it more clear what I have done.)
