how do I link PerlIO Perl package without "installing it"

I'm trying to add the PerlIO::eol package as part of my project without installing it, this way all dependencies can be packaged with my script without having to reinstall them on each machine. How can I do it for PerlIO::eol I don't understand the structure and where the important files are

Solution

Create a subdirectory inc and move an unpacked PerlIO-eol distro there. Then, use something like this in your project's Build.PL:

use Config qw(%config);
use Module::Build qw();

my $build = Module::Build->subclass(code => q(sub ACTION_inc2blib {
    my ($self) = @_;
    chdir 'inc/PerlIO-eol';
    system $^X, 'Makefile.PL';
    system $Config{make};
    chdir '../..';
}))->new(
    module_name     => 'Foo::Bar',
    license         => 'restrictive',
    dist_abstract   => 'blah',
);

$build->dispatch('inc2blib');
$build->create_build_script;

Then, in your main program use blib 'inc/PerlIO-eol';.

But that's BFI, you should simply set up PerlIO::eol as a runtime dependency in your project distro's metafile and have it installed normally.
