First of all, encrypting the script is a red herring, it has nothing to do with the problem. > But, I got 'Unknown PerlIO layer "encoding"' when I run the script. I guessed > the line, binmode STDOUT, ":encoding(UTF-8)"; might cause the problem. Correct. Module::ScanDeps analyzes your script for dependencies and indeed it has a rule ro recognize the pattern ":encoding(FOO)". But then it outsmarts itself and tries to determine which module would actually be required for encoding "FOO" (so that it could just pack in that module). Two problems here: - it overlooks that the machinery to find this module (i.e. Encode.pm) is also needed at script runtime, so at least Encode.pm would have to be packed in any case - it relies on knowledge about the internals of Encode.pm (which might change) As a workaround, add "use Encode;" to your script. I filed RT #72954 to track the actual problem. Cheers, Roderich
