sa-update problem

[askmurphy]

Hello !
Because of the Spamassassin error "FH_DATE_PAST_20XX'' I would like to update the spamassassin software.

So I tried to run 'sa-update'. But this is what I get:
================================================
[root@server01 spamassassin]# sa-update
Can't locate Archive/Tar.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.8.8 /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8) at /usr/bin/sa-update line 81.
BEGIN failed--compilation aborted at /usr/bin/sa-update line 81.
================================================

I have a Centos5-64bits system with Directadmin.

'yum update' and 'yum upgrade' runs ok, no errors.

I would like to fix this problem, but I don't understand what's wrong.
A file is missing ? I hope somebody can help..

Install the Archive::Tar perl module.
