I'm guessing that Net::DNS 0.53 was installed earlier in the @INC Perl 
search path than the RPM version, 0.59, so MailScanner finds it first.

	perl -V

will show you the @INC search path.

I don't know of an easy way of deleting a Perl module that was installed 
with cpan.  I'd probably do:

	locate Net/DNS

and then move all the matches I believed were part of the cpan 
installation to a directory outside the Perl search path.

BTW, you can use rpm to determine if the matched file was installed by rpm:

	rpm -qf /usr/lib/perl5/site_perl/5.8.5/Net/

will tell you which RPM the file was installed by.
