[newbie] rpm 4 macros

[newbie-mandrake]

Greetings!

I'm trying to rebuild postgresql-7.1.1-3mdk.src.rpm in LM72.
Suddenly, It just stop. I looked at the spec file and found out
that it was written in rpm 4 (using new macros). Too bad because
I only have rpm-3.0.5-27mdk.

Macros like %serverbuild.

Can somebody tell me where to find the definition of rpm 4 macros?
If I can just get my hands on LM80, I would execute rpm --eval
%name_of_macro.

Thanks for the time.
