I know. The problem is that the bigger they are, the slower they move...

Okay, I can just about live with the messy spec files. I can't expect to 
retrospectively patch rpmbuild back to RHL7.3... But from .src.rpm 
onwards, a unified build approach would be so much simpler.

I think the mock buildsys-build approach could be extended and 
simplified to help here. At the moment it provides the bare minimum RPMs 
  needed by *every* build and saves cluttering every spec file with 
BuildRequires: bash coreutils, etc., etc..

If OS vendors agreed a common RPM capability naming system along LSB 
lines, then provided buildsys-build-capability packages for all of their 
OS, an ISV could then just require that virtual capability and let the 
builder deduce the BuildRequires.

E.g.
buildsys-build-x11-development.noarch.rpm, Provides: x11-development, 
Requires:  libXrender-devel, libXrandr-devel.. (RHEL5 .noarch.rpm version)

Requires: XFree86-devel (Fedora Core 2 .noarch.rpm version)

Requires: xorg-x11-devel (OpenSUSE 10.1 version)

My .src.rpm:
BuildRequires x11-development
