What about adding "Digest" to your call to Dynlink.add_interfaces?
Dynlink.add_interfaces ["Syntax"; "Digest"; ...] ...
Actually, you should add all standard library modules that the
dynamically-linked module might need, e.g. Pervasives, String, Char,
List, etc.
Yes, it is a pain to list them all, but for dynamic linking of
untrusted code in a secure environment (the initial application of
Dynlink), it must be done this way.
Hope this helps,
