Thanks, Josh.

I was having success with the Net::Braintree module, except for the
method that used the CGI module.  So, I created a simple usertag that
caused the same error:

UserTag test_cgi Order todo
UserTag test_cgi addAttr
UserTag test_cgi Routine <<EOR
use CGI;
sub {
  my ($todo, $opt) = @_;

  my $query_string = $CGI::query_string;
  ::logError("test_cgi tag:".__LINE__.": query_string = $query_string");

  my $query = CGI->new($query_string);
  return $query->Vars;
}
EOR

I placed this usertag in a page called "test.html" and called the
page: /cgi-bin/champnew/test.html?test=1

Error in the global IC error log:

 champnew /cgi-bin/champnew/test.html Died in server spawn: Undefined
subroutine CGI::delete
>  at (tag 'test_cgi') line 9.
