安装qmail-scanner问题－－＞请进!!

./configure --qs-user qscand --qs-group qscand --qmaildir /var/qmail --bindir /var/qmail/bin --qmail-queue-b
inary /var/qmail/bin/qmail-queue --admin postmaster --domain vitalbiotech.com --notify sender,admin --local-domains vitalbiotech.com --lang en_GB --debug yes --unzip yes --scanners clamscan --virus-to-delete yes --install

Testing suid nature of /usr/bin/perl...
Whoa - broken perl install found.
Cannot even run a simple script setuid

You will either have to correct this
or use the C-wrapper within the ./contrib dir

Error was:
Can't do setuid

出现以上错误，不知如何解决？

rpm -qa |grep perl 相看系统中已经随系统安装过：
perl-DB_File-1.804.88
perl-Time_HiRes-1.38-3

多谢！。。。
