Bug 1122498

+++ This bug was initially created as a clone of Bug #1122368 +++

perl-Time-HiRes seems to be a missing requirement when configuring cpan for the first time.

See https://bugs.centos.org/view.php?id=7417 for the details and reproduction steps.

This is a bug in `perl' package. The package should run-require `perl(Time::HiRes)' because Net::Ping module's hires() subroutine loads Time::HiRes:

$hires = 0;
sub hires
{
  my $self = shift;
  $hires = 1 unless defined
    ($hires = ((defined $self) && (ref $self)) ? shift() : $self);
  require Time::HiRes if $hires;
}

There is another issue after proceeding next:

Can't locate local/lib.pm in @INC (@INC contains: /root/perl5/lib/perl5/x86_64-linux-thread-multi /root/perl5/lib/perl5 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 /root) at /usr/share/perl5/CPAN/FirstTime.pm line 1300.

The CPAN::FirstTime module offers local::lib by default if site directories do not exist:

sub _local_lib_config {
    # Set environment stuff for this process
    require local::lib;
    [...]
}

perl-CPAN sub-package should run-require `perl(local::lib)' too.

How to test:

(1) # yum remove perl
(2) # yum install /usr/bin/cpan
(3) # rm -rf ~/.cpan
(4) # cpan </dev/null
Before:
  The reported message is printed and the `cpan' command dies with a non-zero
  exit code.
After:
  The `cpan' command succeeds.
