I took out interpolate=1, develop on RH7.1, IC 4.8.5/4.8.6. The database used 
is postgresql 7.1.2. 

As mentioned, I overlooked the global error log; it mentions 'Attempt to call 
Perl from within Safe'.

I use some library routines included from the catalog.cfg, defined 
in files in the following manner:

##########
Sub library <<EOR
sub {
sub dumpcgi {
# Dump CGI variables in alphabetic order.
        my $page;
        my @keylist=grep $CGI->{$_} ne "" ,sort keys %{$CGI};
        foreach my $x (@keylist) { 
	$page.=$x."=".$CGI->{$x}."<br>\n";
        }
        return $page;
}
}
EOR
##########

Many of these libraries access database tables with the 
Query tag and output HTML.

Hope this clarifies a few things,
