"my_message" is never get printed...
Nor in its current state would you expect it to, why have you put it in an array? Change it to a string like so: 
...
$my_message = 'Hello world Look at my attachment';
$msg = MIME::Entity->build(From    => 'me@myhost.com',
               Type    => "multipart/mixed",
               To      => 'user@company.com',
               Subject => "Hello,  ! ",
               Data    => $my_message);

There, that should've worked.

It gives some bogus cannot access/read-only file error messages...
Adding the actual error message might have helped but as a quick guess I'd say check the documentation for the attach() paramater: Encoding. That's probably the cause?
