If you're trying to find out what modules your program is using, then the following piece of magic may suffice:

END {
  foreach my $file (sort keys %INC) {
    my $module  = $file ;
    my $located = $INC{$file} ;
    $module =~ s|\.pm$|| ;
    $module =~ s|[/\\]|::|g ;
    my $version ;
    { no strict 'refs' ; $version = ${$module.'::VERSION'} || '??' ; }
+ ;
    print STDERR "$module v$version $located\n" ;
  } ;
} ;

if inserted at the start of your program, just before it ends it will print to STDERR all the module file names it has seen require and/or use for. Which may give you a fighting chance of constructing a suitable install package.

Mind you, this will miss any require operations which your test run does not actually execute... I cannot imagine that this will be a problem, but it's tricky to guarantee. If that worries you, you can try:

END {
  my %myINC = () ;
  foreach my $file (keys %INC) {
    my $module = $file ;
    $module =~ s|\.pm$|| ;
    $module =~ s|[/\\]|::|g ;
    $myINC{$module} = $INC{$file} ;
  } ;

  foreach my $module (sort keys %myINC) {
    my $located = $myINC{$module} ;
    my $version ;
    { no strict 'refs' ; $version = ${$module.'::VERSION'} || '??' ; }
+ ;
    print STDERR "$module v$version $located\n" ;

    open my $FH, "<", $located   or die "failed to open $located: $!" 
+;
    while (<$FH>) {
      if ((m/^(?:\s+|[^#;];\s*)*?require\s+([A-Za-z]\w+(?:::\w+)*)\b/)
                                                  && !exists($myINC{$1
+})) {
        printf STDERR " %5d: %s", $., $_ ;
      } ;
    } ;
  } ;
} ;

which has a stab at scanning all the required files, looking for require statements for modules (ignores version numbers) that refer to modules that are not already known.
