>Description:
Yesterday I was unable to install package p5-Data-Dump on NetBSD.

The NetBSD-8.0 system on which the problem was observed is a virtual machine (Virtual Box) sitting on a FreeBSD-11.2 host managed by Vagrant.  The Vagrantfile used to provision the VM calls a shell script which installs various pkgsrc packages and Perl libraries from CPAN.  Whenever a pkgsrc package is available for a given CPAN distribution, I use the pkg.  So, going into this problem, the relevant section of the Vagrant file was this:

#####
     sudo pkgin install \
        p5-CGI \
        p5-JSON \
        p5-JSON-XS \
        p5-HTTP-Daemon \
        p5-HTTP-Message \
        p5-Test-NoWarnings

     sudo pkgin install \
        p5-Data-Dump

     sudo cpan \
        CGI::Utils \
        System::Info \
        Perl::Download::FTP::Distribution
#####

I have called 'vagrant up' or 'vagrant reload --provision' many times on this VM.  The output of 'vagrant reload --provision' would generally contain this output.

#####

In other words, I never got any indication that pkg p5-Data-Dump had *failed* to install.  Nor would I have suspected that p5-Data-Dump would be defective, as I have (a) used the underlying CPAN module, Data::Dump, hundreds of times and (b) I have installed and used the corresponding packages on FreeBSD and OpenBSD many times.

Yesterday, however, I went to run a Perl program which relies on Data::Dump.  The program failed, indicating that Data::Dump could not be located in Perl's @INC, the list of directories which are searched for modules to be loaded.

#####
$ perl -MData::Dump -E 'say q|hello world|;'
Can't locate Data/Dump.pm in @INC (you may need to install the Data::Dump module) (@INC contains: /usr/pkg/lib/perl5/site_perl/5.30.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/site_perl/5.30.0 /usr/pkg/lib/perl5/vendor_perl/5.30.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/vendor_perl/5.30.0 /usr/pkg/lib/perl5/5.30.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/5.30.0).
BEGIN failed--compilation aborted.
#####

I then discovered that p5-Data-Dump had not been installed.

#####
$ pkg_info p5-Data-Dump
pkg_info: can't find package `p5-Data-Dump'
#####

I re-ran 'vagrant reload --provision' several times on the host, with no better results.  Eventually I modifed the Vagrant file to load Data-Dump via the 'cpan' command rather than from pkgsrc.

#####
     sudo cpan \
        CGI::Utils \
        Data::Dump \
        System::Info \
        Perl::Download::FTP::Distribution
#####

Re-running 'vagrant reload --provision', this time CPAN module Data::Dump was clearly installed.

#####

    default:   /usr/bin/make test -- OK
...
    default:   sudo /usr/bin/make install  -- OK
#####

And Perl can now locate Data::Dump.

#####
$ perl -MData::Dump -E 'say q|hello world|;'
hello world
#####

I therefore infer that there is a defect in pkgsrc package p5-Data-Dump.
