I thank everyone for replying. I'd like to report my solution in hopes of helping the next guy with difficulty mailing to Gmail. Email::Send::SMTP::Gmail works well for me, including attachments. There may well be other solutions, but it seems quite simple and works well. Again, assuming I'm "bob" with a "123456" password, the following code works:

   use strict;
   use warnings;
   use Email::Send::SMTP::Gmail;

   my $mail=Email::Send::SMTP::Gmail->new( -smtp=>'gmail.com',
                                           -login=>'bob',
                                           -pass=>'123456');

   $mail->send(-to=>'bob@gmail.com',
               -subject=>'Mail w/attachment test',
               -verbose=>'1',
               -body=>'Test',
               -attachments=>'file.zip');

   $mail->bye;
