cyradm problems

[Jeff Peng]

When I run cyradm I got these errors:

# cyradm
Can't load 
'/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/auto/Cyrus/IMAP/IMAP.so'

I know it's not suitable to ask it here,but I think many people here maybe 
have meet this problem.
Could you give me some suggestion?
The OS is Redhat 9,the Perl version is v5.8.0.
thanks.
