The source in Business/FedEx/DirectConnect.pm does not request those variables:

use Business::FedEx::Constants qw(
    %FE_RE %FE_SE %FE_TT %FE_RQ
    field_name_to_tag
    field_tag_to_name
);
[download]

My guess is that the installed copy of DirectConnect.pm is older than (or at least out-of-synch with) the installed copy of Constants.pm (which is strange, since the installation should take care of both).

Yeah, I'd run it by the IT folks. Alternatively, you could install Business::FedEx::DirectConnect from CPAN off your home directory, but this may be more than you're ready for.
