[ic] Safe error in payment module

[Dan Bergan]

I am playing around with Net::Braintree and trying to use their
Transparent Redirect method.

I have installed Net::Braintree and created a payment module.  When I
process a payment, I am getting the following error:

Safe: Real-time charge failed. Reason: payment routine 'braintreetr'
returned error: Undefined subroutine CGI::delete at
/usr/local/perl-5.8.9/lib/site_perl/5.8.9/Net/Braintree/TransparentRedirect/QueryString.pm
line 18.

line 18 in QueryString.pm:
 my $query = CGI->new($query_string);

Does anyone have any tips for how I can get around this error?

Thanks -
