Today I attempted to install FreeBSD port 'p5-Devel-Cover' on FreeBSD-12. The system 'perl' on this machine was perl-5.32.0. I ran into problems which suggest that the p5-Devel-Cover port needs revision. ##### $ uname -mrs FreeBSD 12.2-STABLE amd64 $ sudo pkg install p5-Devel-Cover Password: Updating FreeBSD repository catalogue...

[5/5] Extracting p5-Devel-Cover-1.36: 100% ##### So far, so good -- but when I went to run 'cover' on a Perl library I've written, I got: ##### $ cover -delete; harness; cover -report=text > $P5P_DIR/multisect/`extract-sha`.coverage.txt This version of Devel::Cover was built with Perl version 5.032001.

This version of Devel::Cover was built with Perl version 5.032001. It is now being run with Perl version 5.032000. Attempting to make adjustments, but you may find that some of your modules do not have coverage data collected. You may need to alter the +-inc, +-ignore and +-select options. Can't locate B/Debug.pm in @INC (you may need to install the B::Debug module) (@INC contains: /usr/home/jkeenan/gitwork/devel-git-multibisect/blib/lib /usr/home/jkeenan/gitwork/devel-git-multibisect/blib/arch /usr/local/lib/perl5/site_perl/mach/5.32 /usr/local/lib/perl5/site_perl /usr/local/lib/perl5/5.32/mach /usr/local/lib/perl5/5.32 .) at /usr/local/lib/perl5/site_perl/mach/5.32/Devel/Cover.pm line 28.

BEGIN failed--compilation aborted. t/001-opts.t ..................... Dubious, test returned 2 (wstat 512, 0x200) No subtests run ... [snip: all other test files fail in the same way] ##### I addressed the Perl version clash by upgrading the 'perl5' package to 5.32.1. That proceeded without incident. I then looked at the apparently missing prerequisite B::Debug. The 'corelist' utility tells me that this module no longer ships with the Perl 5 core distribution: ##### $ corelist B::Debug Data for 2020-06-20 B::Debug was first released with perl 5.005, deprecated (will be CPAN-only) in v5.27.3 and removed from v5.29.4 ##### I searched for B-Debug at FreeBSD Ports Search, but no Perl 5 program was listed. ##### https://www.freebsd.org/cgi/ports.cgi?query=B-Debug&stype=all&sektion=all ##### I then installed B::Debug directly from CPAN. It installed successfully ... and then to my surprise subsequently installed B::Flags in the same 'cpan' session. ##### RURBAN/B-Debug-1.26.tar.gz /usr/bin/make install -- OK ... RURBAN/B-Flags-0.17.tar.gz /usr/bin/make install -- OK ##### It turns out that there *does* exist a FreeBSD port for B::Flags: ##### https://cgit.freebsd.org/ports/tree/devel/p5-B-Flags ##### ... but this *does not* appear to include B::Debug. Action Items 1. There should be a FreeBSD port for CPAN distribution B-Debug. 2. The FreeBSD port for Devel-Cover (p5-Devel-Cover) needs to have a prerequisite added for the port for B-Debug requested in the preceding item. Thank you very much. Jim Keenan
