in reply to Storable: Cannot restore overloading on SCALAR

Do both systems have JSON::XS installed, and if so what version does each have? From the manpage of JSON::XS::Boolean (which is part of the JSON::XS distribution):

This module exists only to provide overload resolution for Storable and similar modules. It's only needed for compatibility with data serialised (by other modules such as Storable) that was decoded by JSON::XS versions before 3.0.

Since 3.0, JSON::PP::Boolean has replaced it. Support for JSON::XS::Boolean will be removed in a future release.
