More details. We can try to help...

Yes, there are several rpmmacros Axel uses that you would need to have 
defined in order to build straight off his spec files. They require 
some fairly heavy hacking to get around that, but it can be done (I've 
done it myself for other ATrpms packages), but you have to install the 
.src.rpm file, edit the spec file, then rpmbuild -ba ivtv.spec.

Well, ivtv is NOT in the mythtv-suite dependency chain. No drivers are, 
only software components, since people use a variety of different 
drivers for different cards. The only deps to worry about are 
perl-Video-ivtv and perl-Video-Frequencies, I believe, which are 
explicitly defined as deps in the spec file, so you won't be breaking 
any dependency chains if you alter the macros in the spec file for 
which you don't have definitions.
