The issue seems to involve the "Module::Installed::Tiny dependency tree" — that doesn't look very Tiny to me.

Sheesh! I never noticed that. The deps are ALL related to test prereqs.

I liked the premise of the distribution, so I wrote my own. Module::Installed. It not only checks single modules, but I added a function that will list all includes in a file and whether or not they are installed or not. There are no non-core deps. PPI is required to use the includes_installed() function, but we load it dynamically only if it's available:

use warnings;
use strict;

use Data::Dumper;
use Module::Installed qw(module_installed includes_installed);

my $module = 'PPI';
my $file = '/home/spek/repos/module-installed/t/data/test.pl';

my $statement = module_installed($module)
    ? "is installed"
    : "isn't installed";

print "$module $statement\n\n";

print "Checking includes in file $file\n\n";

my $includes = includes_installed($file);

print Dumper $includes;

Output:

PPI is installed

I just finished a very large Perl project that I landed a little while ago. It's nice to be back in the Perl mindset, hammering out all manner of weird stuff. I'll take a look at the "bareword" issue in Syntax::Check later this afternoon.

Update: Holy crap, I just realized I've hit the 50 mark in published CPAN distributions!
