Well the best way of solving this problem is to indicate to your boss
his/her requirement is nonsense and that the version number itself
doesn't indicate anything.
But if that doesn't work, fix stupid requirements with stupid solutions.
Write a dummy module like:
use vars '$Version';
# Leave next 2 lines out if XML::Parser::PerlSAX doesn't
# use Exporter.
@ISA = 'Exporter';
$VERSION = 1.1;
Alternatively, assuming XML::Parser::PerlSAX
is free software,
copy it, and change the version number in your copy.
