Sorry, this won't work since Lingua::EN::ABC loads abc.json with

my $json = __FILE__;
$json =~ s!\.pm$!/abc.json!;
my $abc = json_file_to_perl ($json);

There are two problems here:

(1) There's no way that Module::ScanDeps can figure out from scanning Lingua/EN/ABC.pm
that it should add a dependency on Lingua/EN/ABC/abc.json. Hence this file will not
be packed by pp into your executable.

(2) But even if it were packed the above will fail to load it, as __FILE__ is set to
"Lingua/EN/ABC.pm" (note the absence of a directory) when the module is loaded running
in a packed environment.

In theory (1) can be solved with minimal effort by adding a special rule to
Module::ScanDeps, but that still leaves (2).
