[Cooker] Perl-Base / Postgresql-PL problem

[Digital Wokan]

Installing perl-5.8.1-0.RC4.2mdk.i586 requires removing 
postgresql-pl-7.3.4-1mdk.i586 due to unsatisfied perl-base == 5.8.1

So I'm guessing RPM doesn't see perl-base-5.8.1-0.RC4.2mdk.i586 as 
providing perl-base == 5.8.1 for some reason.
