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();
