I ran into this same problem, upgrading to 0.65. Jeff (Allen) was aware of the problem, but it was not causing him problems, because of the behavior of his webserver (Apache).
Since I am using Netscape Enterprise server, I investigated this on my own.
The problem, is that the router-interfaces style configuration files, use a perl function "map()". The 'use Strict' declaration at the begining of grapher.cgi causes the map
function to complain about the potential keyword "interface", which is part of the "interface-name" option.
I fixed the problem by quoting the map function argument.

my(@inst) = ();
! if ($needEval) {
! $inst =~ s/^map\((.*)\)$/map(qw($1))/;
! @inst = eval($inst);
! }
if ($#inst+1 > 1) {
# make the instance selection widget...
--- 156,162 ----
};
my(@inst) = ();
! @inst = eval($inst) if ($needEval);
if ($#inst+1 > 1) {
# make the instance selection widget...
