PL/Perl trusted throws error on example function

Hi,

I tried to test plperl and got the following error with the very first
example from chapter 37:

CREATE OR REPLACE FUNCTION perlmax(integer,integer)
RETURNS integer AS $$
if ($_[0] > $_[1]) { return $_[0]; } return $_[1];
$$ LANGUAGE plperl;

--
error from Perl function: trusted Perl functions disabled - please
upgrade Perl Safe module to version 2.09 or later at (eval 4) line 1.

PostgreSQL is 8.0.1, System is SuSE 9.2 (64 bit) on AMD64. Perl Safe
module says, it__s version 2.11, which seems to be the latest release on
CPAN.

plperl is installed as "trusted". If I install it as plperlu
"untrusted", the example above works correctly.

What is so bad with this function that I only can run it untrusted?

Regards, Frank
