RPM Building issue: can't find .i386 temp buildroot file

[Rwac]

I'm testing out building an RPM for just script/conf files, the actual contents of the RPM would be many scripts/conf files etc. In this situation it is necessary to distribute it as an RPM:

The spec file, directory structure

[rwac@aputer SPECS]$ pwd
/home/rwac/rpmbuild/SPECS
[rwac@aputer SPECS]$ ls filebroker.spec
filebroker.spec
[rwac@aputer SPECS]$ ls ../
BUILD BUILDROOT RPMS SOURCES SPECS SRPMS

What happens when I try to build the rpm...

[rwac@aputer SPECS]$ rpmbuild -ba filebroker.spec
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.ZtWSwz

The source (a compressed folder containing 2 dummy files)

[rwac@aputer SPECS]$ ls ../SOURCES/filebroker-1.0.tar.gz

The spec file culprit - have been commenting out to try and isolate where the issue lies

- First Version

Naturally, there is no requirement to specify anything within %build as this will simply throw the relevant files around. When I have resolve this rpm building issue, the %prep section will include creating the appropriate binary directories etc.

Does anyone know how I can resolve this issue? System is Fedora 12 i686.

Edit:
I note that the arch references in /usr/lib/rpm/macros are i386:

$ cat /usr/lib/rpm/macros | grep %_build_arch
%_build_arch i386
$ cat /usr/lib/rpm/macros | grep %_arch
%_arch i386

Whilst uname -p shows:
$ uname -p
i686
