exact same error message I'm getting now.. The only thing I can think of is an upgrade to the latest version of perl from redhat.
Here are the two entries from my log file when this error occurs.
/etc/sendmail.cf: line 83: fileclass: cannot open '/etc/mail/local-host-names': World writable directory
/etc/sendmail.cf: line 508: fileclass: cannot open '/etc/mail/trusted-users': World writable directory
