+++ This bug was initially created as a clone of Bug #1903503 +++

Description of problem:
The package perl-MIME-Types should pull in the package perl-Encode as dependency. Otherwise the package is unusable:

How reproducible:
always

Steps to Reproduce:
1. yum install perl-MIME-Types
2. Run the following perl script:
-----------------------------------------------
#!/usr/bin/env perl

use warnings;
use strict;
use MIME::Types;

my $mt = MIME::Types->new;

my @types = $mt->listTypes();

foreach (@types) {
        print("$_\n");
}
-----------------------------------------------

Actual results:
cannot open type database in /usr/share/perl5/vendor_perl/MIME/types.db: No such file or directory

Expected results:
message/cpim
message/delivery-status
message/disposition-notification
[...]

Additional info:
Problem is fixed by running:

I looked deep on it and I found the source the issue.

lib/MIME/Types.pm 
42:    open DB, '<:encoding(utf8)', $db
43:       or die "cannot open type database in $db: $!\n";

open(,':encoding()',) is loading 'PerlIO::encoding'. 'Encode' is loaded in BOOT section of 'PerlIO::encoding'. This require is not found by perl-generators.

'PerlIO::encoding' is provided by perl-libs. So, we have to add 'Encode' to perl-libs as a run-require.
