rpm-3.0 works, rpm-4.0.3 does NOT

[paul company <pjc noyb com>]

I built and installed rpm-4.0.3 successfully.

But when I tried to build it as a package, I got the following error:

============BEGIN ERROR MESSAGE=================
# rpm -bp spec.rpm-4.0.3-1
Executing(%prep): /bin/sh -e /var/local/tmp/rpm-tmp.1314

RPM build errors:
    Bad exit status from /var/local/tmp/rpm-tmp.1314 (%prep)
=========== END ERROR MESSAGE ===========

When I use the same spec file with rpm-3.0 everything works fine.
What generates the rpm-tmp.1314 file?
It looks like this is the problem.
Why does it try to "cd" into the same directory twice?
Why is the tar line incorrect?
etc. etc.

Any ideas?

Also, what's the difference between versions 3.x and versions 4.x?

Here's my spec file:
