build-from-tarballs is far from ideal, certainly.  It was good enough to get 
7.0 bootstrapped, and hasn't really seen much love since then.

Here's the thing.  Of the people who want the ability to build the world from 
source without relying on external packaging, no one has come up with 
anything better.  Many people have said they would _like_ something better; 
I've not seen anything _done_.  Oh, except for the jhbuild stuff, but then no 
one wants to use jhbuild, they just want something "simple" like a shell 
script, even though to make one complex enough to handle rebuilding all of X 
from scratch, you very nearly have to reinvent jhbuild.

You might be better served to just reuse the packaging that already exists for 
rawhide, and use mock to rebuild those SRPMs against FC4.  I believe Mike's 
done it, and it's probably less painful that trying to fix up the tarball 
script.  For that matter, you could very likely just _install_ the built 
rawhide SRPMs with 'rpm --nodeps' on an FC4 system with no X installed and 
get what you want.

In fact, this comes up often enough that I'm tempted to just build an FC4 yum 
repo with X bits that match rawhide.
