creating rpms with a specfile from a repository

I was working with my varnish vmod today, attempting to package it into rpm. I found a useful tutorial here: https://fedoraproject.org/wiki/How_to_create_an_RPM_package

I tend to be a bit impatient though and I didn't read everything. I wanted to have my rpmbuild process checkout the code from a repo and then to ./configure && make but I ended up getting this odd error:

error: No "Source:" tag in the spec file

It took a little while to get to the bottom of things, but I eventually discovered by having the following macro in my .spec file 

%setup -q

caused rpmbuild to need a Source: line. Once I took that line out, all was good again. The spec files I built are for libmaxmindb, varnish cache and a varnish module. The code is here:
