redhat-rpm-config has been in the base SL repo since SL 6.0, in 2011.  
See 
ftp://ftp.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/redhat-rpm-config-9.0.3-25.el6.noarch.rpm

It's easy to miss since it previously wasn't a hard requirement for 
rpm-build, but it's been there since the beginnings of SL6.

I actually appreciate your posting of the workaround, since for 
package-building for EL5 I have kept an EL5 buildhost for some internal 
packages, since I hit this with EL6.0 back in 2011.  But I have 
installed redhat-rpm-config as part of my standard package-building 
installation in EL6 since I first started using EL6 (I use CentOS 6 for 
the most part, but CentOS and SL are almost identical for my purposes).

I understand your frustrations.

You could probably report it to Red Hat's bugzilla, but it would likely 
be closed WONTFIX.
