Well yes, but

In fact,

Well yes, but

'~/perl5/bin' ne '/bin'

What does that mean?

In fact,

$ echo $PERL_LOCAL_LIB_ROOT 
/home/choroba/perl5

My environment doesn't have that variable. How does it help isolate executables from CPAN? I guess it does help isolate core perl programs, like this:

#!/usr/bin/perl -l

use strict;
use warnings;

# List executables installed by Perl core
# List CPAN: https://perlmonks.org/?node_id=1217338

(my $bin = $^X) =~ s/.perl$//;
chomp(my @perl = `ls -l $bin`);
s/.*\s(\S+)$/$1/ for @perl; # filename
shift @perl;

chomp($_ = join "", `perldoc -uT perllocal`);
my @temp = (/EXE_FILES:\s([^>]+)/sg);
my @cpan = ();

for (@temp) {
   my @x = split /\s+/; # filename(s)
   s/^\S+\/// for @x;   # remove path
   push @cpan, @x;
}

my $perl = { map {$_=>1} @perl };
my $cpan = { map {$_=>1} @cpan };
my $core = {};

for (keys %$perl) { $core->{$_}++ unless $cpan->{$_} }
print $_ for sort keys %$core;
