dag repo and perl dependencies naming

[sophana at zizi.ath.cx (sophana)]

Hi

I'm trying to install amavisd-new from dag repo on centos3.
In the spec file perl dependencies use parenthesis: perl(Digest::MD5)
it also uses '-': perl-MailTools

The problem is that only the second notation is available: perl-MD5

I know this is an old problem. Is this only centos related?
Is there a workaround?

Do I have to modify the spec file? I'd like to use yum...

Regards
