Installing on Mandrake 9.2

[Brian Parish]

I have installed MailScanner successfully on previous Mandrake releases,
but always have to mess around with various perl issues.  On this 9.2
install with all updates applied, I get the usual:

------------
Attempting to build and install perl-IO-stringy-2.108-1
/usr/lib/rpm/rpmb: No such file or directory
Missing file
/usr/src/RPM/RPMS/noarch/perl-IO-stringy-2.108-1.noarch.rpm.
Maybe it did not build correctly?
------------

stuff, but: perl-IO-stringy-2.108-6mdk

is installed, so this and all the following perl complaints are
presumably of no significance.  However this is:

# service MailScanner start
Starting MailScanner daemons:
         incoming sendmail:                                     [  OK  ]
         outgoing sendmail:                                     [  OK  ]

Can anyone shed any light on what's going on here?

TIA
