 * try to figure out if there is some desired order of keys
 (perl5.branches/perl5.setup/licence/maintainer/...)
   * properly implement `if {${perl5.major} != ""} {` and put dependencies
 inside the block
   * description is often missing, but `META.yml` usually contains
 `abstract:` that could be used
   * sort dependencies alphabetically
   * something seems to be wrong with dependencies, see `cpan2port -t
 Mouse` for example:
 {{{
 build_requires:
   Test::Exception: 0
   Test::Exception::LessClever: 0
   Test::Fatal: 0
   Test::LeakTrace: 0
   Test::More: 0.88
   Test::Output: 0
   Test::Requires: 0
   Try::Tiny: 0
 configure_requires:
   CPAN::Meta: 0
   CPAN::Meta::Prereqs: 0
   Devel::PPPort: 3.19
   ExtUtils::ParseXS: 3.22
   Module::Build: 0.4005
   Module::Build::XSUtil: 0
 requires:
   Scalar::Util: 1.14
   XSLoader: 0.02
   perl: 5.008005
 }}}
 But it generates:
 {{{
     depends_build-append \
                     port:p5${perl5.major}-test-exception \
                     port:p5${perl5.major}-test-exception-lessclever \
                     port:p5${perl5.major}-test-fatal \
                     port:p5${perl5.major}-test-leaktrace \
                     port:p5${perl5.major}-test-output \
                     port:p5${perl5.major}-test-requires \
                     port:p5${perl5.major}-try-tiny
 }}}

 In particular `Module::Build::XSUtil` and everything else from
 `configure_requires` is missing, as well as runtime dependencies.
