Why don't p5-* ports mark their dependencies?

Thank you, that worked and allowed me to uninstall all p5.28 modules.

What puzzles me still, why port info shows that git depends on perl 5.28 modules:

$ port info git          
git @2.32.0 (devel)
Variants:             [+]credential_osxkeychain, [+]diff_highlight, [+]doc, gitweb, [+]pcre, perl5_26, [+]perl5_28,
                      perl5_30, python, svn, universal

$ port installed and git
The following ports are currently installed:
  git @2.31.1_2+credential_osxkeychain+diff_highlight+doc+pcre+perl5_30
  git @2.32.0_0+credential_osxkeychain+diff_highlight+doc+pcre+perl5_30 (active)


git works, as far as I can test. 

Thanks,
