These just build ISOs, right?  I can do that already with your RPMs and
SRPMs. That isn't my question.

Where are the scripts you use to turn SRPMs into RPMs? Suppose I want to
re-build everything from source? (you do that, right?)

Yes, most SRPMs just work with "rpmbuild -bb <package.spec>". But the
kernel-smp and the compiler don't 'just work' on rebuild.

I'd like to build kernel-smp from SRPM. The distributed SRPM identifed
by the distributed RPM doesn't have a package for kernel-smp.  Perhaps
there are two SRPMs with the same name and only one is distributed.  
Perhaps there are some environment variables passed in to rpmbuild by
the build scripts:

Summary     : The Linux kernel compiled for SMP machines.
Description :
This package includes a SMP version of the Linux kernel. It is
required only on machines with two or more CPUs, although it should
work fine on single-CPU boxes.

Install the kernel-smp package if your machine uses two or more CPUs.

If there are environment variables, command line options, or non-generic
macro files, these need to be identified or distributed.  Anything that
deviates from a generic installation should be noted.

Apparently not.  rpmbuild doesn't build the RPM from the SRPM.  I get
errors on missing 64bit librarires, regardless of whether the build is
done in sparc32bash or not.  Perhaps your build machines have different
rpm macros, environment, or something.

It sounds to me like you might not rebuild everything from source using
a generic-installation system for the distribution. We used to call that
'self-hosting' Do you do that?  If so, what exactly are the
specifications of those machines?
