Here's a chunk of code that is in production at my office: 
my $subject = "FLR invoices";
my $msg =
        MIME::Entity->build(
                From    => SOURCE,
                To      => TARGET,
                Subject => $subject,
                Type    => "multipart/mixed",
                );

my $textpart = <<END;
Attached is the XML file $xmlfile.

END

# Add the text greeting
$msg->attach(
        Type            => 'text/plain',
        Encoding        => '7bit',
        Data            => $textpart,
        );

# Add the XML file
$msg->attach(
        Type            => 'text/xml',
        Encoding        => 'base64',
        Description     => "XML file $xmlfile",
        Path            => $xmlfile,
        );

$msg->send( 'sendmail' );

Note that the body is specified thru a variable, and the attachment is a file. I'm pretty sure you don't have to specify a filename when you create the attachment.

Andy
