Greetings Monks

I copied the sub "dec2bin" from section 2.4 "Converting Between Binary and Decimal" in the Perl Cookbook (page 48 in my copy).

    sub dec_to_bin {
        my $flag = shift ;
        my $str = unpack("B32", pack("N", $flag)) ;
        $str =~ s/^0+(?=\d)// ;
        return $str ;
    }

When I run it, I get this strange warning ...

Ambiguous call resolved as CORE::unpack(), qualify as such or use & at ./utils.pl line 190.
Ambiguous call resolved as CORE::pack(), qualify as such or use & at ./utils.pl line 190.

The result seems OK to me -- so what is the problem? Anyone here know?

The OS is FreeBSD.
