Thanks for the response. I added a rewind thusly: 
######################################################################
# This doesn't
{
  my $ua = LWP::UserAgent->new;
  $ua->timeout(10);
  $ua->env_proxy;
  my $response = $ua->get($url);
  
  my $tmp = File::Temp->new();
  if ($response->is_success) {
      binmode($tmp);
      print $tmp $response->decoded_content;
      print "Wrote ".$tmp->filename()."\n";
      $tmp->seek(0,0); # Added rewind
  }
  else { die "error ".$response->status_line; }
  
  unless (-B $tmp) { die "Did not get a filehandle\n"; }

  my $zip = Archive::Zip->new();
  my $zip_err = $zip->readFromFileHandle( $tmp );
  unless ($zip_err == AZ_OK ) {
    die "Archive::Zip read error on filehandle: $zip_err\n";
  }
  
  foreach my $member ($zip->members()) {
    my $fileName = $member->fileName();
    print "fileName = $fileName\n";
    my $content = $member->contents();
    print "contents $fileName = ".Dumper($content);
  }
}

which didn't appear to affect the issue.
