Great! At least I am not completely confused :-) Ok, will build the srpm 
then and take it from there, thanks Brian!

Before I go back to my cave, can you suggest any up to date howto pages 
for CBS/koji? http://wiki.centos.org/HowTos/CommunityBuildSystem has been 
mentioned to me, but it is really a quickstart page and also is talking 
about git builds which if I am reading correctly your reply are not there 
yet, at least not for new packages...
