The only thing you can do currently is to look a the list of
dependencies on the CPAN website and copy that into depends_lib of your
new p5-* port.

The long-term solution would be to make cpan2port usable. This is a
project which Marc Chantreux (mc@) began to work on, but it did not
advance much since then. I think we need a person with experience in
Perl/CPAN here.

The script is written in Perl, which is good taking into account that
this integrates best with existing architectures.

How would you know this not using MacPorts? CPAN?

At best, the description for Tie::DBI can note Tie::RDBM. Again,
cpan2port could help maintaining dependencies for p5-* ports.

If the module has its own test cases you can run them using port. As the
perl5 port group already defines 'test.run yes', it assumes all modules
come with test cases. So you only need to run `port test`.
