This may get you more than you want, but does provide a lot of information. You can play with the -select an -ignore settings of Devel::Cover ...

mkdir /tmp/myscript_cover 
perl -MDevel::Cover=-db,/tmp/myscript_cover,-select,. /tmp/myscript.pl

I ran this against: the following, and was able to see the used modules in the Devel::Cover output.

use strict;
use File::Path;
mkpath '/tmp/asdasd';
use Image::Magick;
my $IMG_BLANK = Image::Magick->new();
