Well, the advice I gave you was a way to get the package build, don’t
know what’s wrong with my explanation, macros such as %configure2_5x are
also made to make your life easier like, not worry if the package is
located in the right place, or has the correct CFLAGS ;)

That’s because some of our macros differ from fedora. I don’t know what
macro they use, but assuming they also don’t diverge on their location,
you could try to have a look at /etc/rpm/macros.d/.

Also, as I said, rpm --eval could help you see the difference too :-)

I just imported http://mageia.org/wiki/doku.php?id=spec_syntax if you
want to take a look, the RPM Howto [1] hasn’t been imported yet, would
you like to step up to help us ? :-) It could help you understand the
different sections by reviewing them carefully. Also, since this howto
is designed to help new packagers, it will also help us clarify some
things that may not be as clear as we meant it.
