t/ack-man.t and t/invalid-ackrc.t fail on FreeBSD

[rosorio]

Running package test on FreeBSD return the following errors, this is true on 3.10.0 but also in 3.9.0
This is not a blocker to update the port but something si probably missing

⓪ It's nice to hear that *BSD packaging is happening! ❤️ 👍

① The Man-Pod-Perldoc issue is a known Perldoc issue with Perl itself. Perl/perl5#13009
Many years ago, Perldoc would fall-back to emitting the plain POD as-is if no NROFF or equivalent text processor was found to re-format text nicely for the terminal. But sometime over a dozen years ago [Perl 5.16.x , 2012] , this no nroffer message was inserted and the fall-back omitted.
(Essentially, this is caused by some Linux and BSD distros making core POSIX components such as nroff into optional packages, which no-one lists as dependencies since they're considered core by everyone else.)
FreeBSD has an nroff package; if you install that, one expects Perldoc will find it and this would work? If so, perhaps you can add it to the package Test Requires list?

② The t/invalid-ackrc.t failure is a subtest of 'Check --env --man' and so is just a cascading-failure from not having output for --man; this is a noisy echo from ① above.
