Here's a template that should work - I haven't tested it, but it's
similar enough to others I have done.  You would invoke cfgmaker as:
/usr/local/mrtg-2/bin/cfgmaker --if-template=pps.template --ifref=name
--subdir=HOSTNAME public at myrouter.com --output=myrouter-pps.cfg

if (not $problem_lines) {
my $max_packets = int($if_speed / 64);
#correct for IFG and preamble
$max_packets = int($if_speed / 74) if $if_is_lan; 

$target_lines .= <<ONETARGET
Target[$target_name]: ifInUcastPkts.$if_ref&IfOutUcastPkts.$if_ref:$router_connect +
Directory[$target_name]: $directory_name
