Try

 print Delta_Format($dtopt,0,'+%yv:%Mv:+%wv:%dv:%hv:%mv:%sv');

instead of your print line.

It's probably not the newer Perl that bites you, but rather the newer Date::Manip module that you are using.
Try to check what you have in Date::Manip::DM6.

A bit strange; the raw value that I see for the delta calculated from the date values you provided is 0:0:0:110:0:0:0, which isn't equal with what your systems are giving.
