Tanx very much.

Now I have only another question.
To save time on rebuild there is a way to not uncompress every time the
source into the BUILD dir?

I see that in spec file there is a %prep section in which the source are
uncompressed.
This appens every time i run the rpmbuild -ba ...
In the section I see the %setup command but I don't know how %setup is
defined.

There is a rpmbuild option
